Description

Technical Field

[0001] This invention relates to the field of floating nest technology, and in particular to an aquatic ecological floating nest for attracting Baer's Pochard to breed. Background Technology

[0002] Baer's Pochard ( Aythya baeri The Baer's Pochard (Amur Pochard) belongs to the order Anseriformes and the family Anatidea. It is a migratory pochard found along the East Asian-Australasian Flyway. Since the 1990s, its population has been declining, leading to its classification as a critically endangered species and a Class I protected wild animal in China. The scarcity of the Baer's Pochard population has attracted significant attention both domestically and internationally. With a wild breeding success rate of only 23%, improving the breeding success rate of the Baer's Pochard is urgently needed.

[0003] One reason for the sparse population of Baer's Pochard is habitat loss and degradation, especially the absence and decline in the quality of its breeding habitat. Reproductive success is the most direct and important driver of bird population growth. Based on eight consecutive years of field surveys and monitoring, Baer's Pochards typically nest on earthen embankments or mounds surrounded by water with high vegetation cover. Therefore, their reproduction is affected by water level changes and a lack of suitable nesting sites, leading to nest flooding and breeding failure. Eight years of in-depth research into the reproductive ecology of Baer's Pochards revealed that factors influencing nesting success include the height of the nest above the water surface, the distance of the nest from the pond bank, and vegetation cover. Furthermore, the survey found that brood parasitism occurred in 42% of Baer's Pochard nests; this high rate and intensity of brood parasitism indicate a lack of suitable nesting sites. In conclusion, providing suitable nesting conditions for Baer's Pochards is of great significance for improving their reproductive success.

[0004] Therefore, in order to effectively save this critically endangered species, there is an urgent need for a new type of floating aquatic ecosystem to attract Baer's Pochard to breed and solve the above-mentioned technical problems. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problems, namely, to solve the following problems existing in the natural nesting sites in the wild: water level fluctuations can easily lead to the nest being flooded; nests near the shore are easily preyed upon by terrestrial predators; and the scarcity of suitable nesting sites leads to nest parasitism, which affects the egg hatching rate and the survival rate of chicks.

[0006] To this end, the present invention provides a nature-based solution: an aquatic ecological floating nest for attracting Baer's Pochards to breed, comprising a floating platform, a planting trough, a fixed post, and a remote monitoring system. The lower section of the fixed post is buried in the bottom mud layer of a designated water area, and the top of the fixed post extends above the water surface. The floating platform is fitted onto the fixed post and can move up and down with changes in water level to always float on the water. The planting trough is nested on the floating platform and its bottom is submerged in water. The planting trough is planted with vegetation that provides shelter and nesting material for the Baer's Pochards. The remote monitoring system is installed at the top of a fixed post for remotely monitoring the floating nest and its surrounding environment. It is configured to remotely transmit image information to trigger an alarm when predators approach or enter, and can also monitor the surrounding environment and the usage of the floating nest.

[0007] In the specific embodiment of the above-mentioned floating ecological nest for attracting Baer's Pochard to breed, the floating platform is a ring-shaped cylinder, the planting trough is nested inside the floating platform, and the planting trough is a hollow basket structure.

[0008] In the specific implementation of the above-mentioned floating ecological nests for attracting Baer's Pochard to breed, the vegetation includes perennial aquatic or semi-aquatic plant species, the vegetation height is not higher than 1.5 meters, and the coverage is not less than 70%.

[0009] In the specific embodiment of the above-mentioned floating ecological nest for attracting Baer's Pochard to breed, three sleeves are nested on the floating platform outside the planting trough, arranged in a congruent triangular array on the horizontal plane. Each sleeve has a fixed column passing through it, so that the floating platform can move up and down along the fixed column.

[0010] In the specific embodiment of the above-mentioned floating ecological nest for attracting Baer's Pochard to breed, the remote monitoring system includes a monitoring probe and a support. The support is installed on one of the fixed columns, and the length of the fixed column is greater than the length of the other fixed columns. The monitoring probe is installed at the top of the support and faces the planting trough. The monitoring probe has a built-in audible and visual alarm to drive away invading predators.

[0011] In the specific embodiment of the above-mentioned floating ecological nest for attracting Baer's Pochard to breed, the distance between the outer edge of the planting trough and the outer edge of the floating platform is 12-18cm, and the top of the fixed column is more than 50cm above the highest water level in the area.

[0012] In the specific embodiment of the above-mentioned floating ecological nest for attracting Baer's Pochard to breed, the outer surface of the fixing post is coated with an anti-corrosion coating, and the lower section of the fixing post is provided with a spiral anchoring structure.

[0013] In the specific embodiment of the above-mentioned floating ecological nest for attracting Baer's Pochard to breed, the floating ecological nest further includes an intelligent weight monitoring device. The intelligent weight monitoring device includes a miniature weight-sensing scale, a transmission line, and a data acquisition and transmission module. The miniature weight-sensing scale is installed in the middle part of the planting trough or at the bottom of the planting trough, and is connected to the data acquisition and transmission module through the transmission line to transmit the detected weight information to the data acquisition and transmission module for monitoring weight changes and transmitting it over long distances. The data acquisition and transmission module is encapsulated on the floating platform.

[0014] In the specific embodiment of the above-mentioned floating ecological nest for attracting Baer's Pochard to breed, the miniature weight-sensing scale frame includes a miniature weight sensor and a scale frame. The scale frame is buried in the middle or bottom of the planting trough. The scale frame is in the shape of a circular tray, and the bottom of the circular tray is a screen structure. The miniature weight sensor is installed in the center of the bottom of the scale frame. The data acquisition and transmission module includes a pressure sensor digital conversion module, a microcontroller main controller, and a (Bluetooth version) intelligent serial port data logger connected in sequence. The miniature weight sensor is connected to the input end of the pressure sensor digital conversion module. It can be paired and connected with the intelligent weight monitoring device via Bluetooth through a mobile phone, and can acquire real-time recorded data. At the same time, all weight recorded data can be downloaded.

[0015] In the specific embodiment of the above-mentioned floating ecological nest for attracting Baer's Pochard to breed, the floating ecological nest for attracting Baer's Pochard to breed also includes a power module installed on the floating platform, which provides power to the remote monitoring system and the intelligent weight monitoring equipment.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. The ecological floating nest designed in this invention floats at a designated location in the water and can move up and down with changes in water level, ensuring that the floating nest always stays afloat. This effectively prevents the Baer's Pochard from failing to reproduce due to the eggs being submerged by rising water levels, overcoming the technical obstacle that natural nest sites cannot adapt to dynamic water level changes. Furthermore, the ecological floating nest can be flexibly installed in various locations according to local conditions, allowing it to be located far from the shore, effectively avoiding predator threats to the Baer's Pochard eggs and improving the breeding success rate. In addition, since the number of ecological floating nests can be increased significantly, the occurrence of brood parasitism is reduced, which is beneficial to improving egg hatching rate and chick survival rate.

[0017] 2. A remote monitoring system is installed on the fixed post to monitor the breeding behavior of Baer's Pochard, the environment around the floating nest, and the activities of natural enemies. This enables remote scientific research monitoring and emergency control, reducing interference from scientific research activities.

[0018] 3. By mounting the floating platform on fixed posts arranged in a congruent triangular array, the risk of the floating nest overturning can be avoided. Combined with the structural features and dimensions of the present invention, it can provide the Baer's Pochard with a nest site structure and selective characteristics that conform to its ecological habits, thus having an attractive effect in the wild. The aquatic ecological floating nest designed in this invention is a single nest design, which effectively solves the problems of excessive nest density of the same species caused by nest site competition and mutual interference between species during the incubation and brooding period. The present invention, in the form of a floating nest, is far away from the land shore, effectively avoiding interference from natural enemies and ensuring the safety of the Baer's Pochard during egg laying and incubation.

[0024] To reduce breeding failure caused by flooding, improve the breeding success rate of Baer's Pochard, and increase its population, this invention provides a nature-based solution (NbS), namely, an aquatic ecological floating nest designed to attract Baer's Pochards for breeding, based on their nesting site selection characteristics. Nature-based solutions refer to actions that protect, sustainably manage, and restore natural and altered ecosystems, effectively and adaptively addressing societal challenges while providing human well-being and biodiversity benefits. The International Union for Conservation of Nature (IUCN) and the Convention on Biological Diversity advocate relying on the power of nature and ecosystem-based approaches to address societal challenges such as ecosystem degradation and biodiversity loss. This ecological floating nest can be installed in environments such as ponds, lakes, and rivers where Baer's Pochards breed. It maintains a stable distance from the water surface regardless of water level rises or falls, overcoming breeding failures caused by flooding, predation, and human interference. It also provides suitable nesting sites for breeding individuals and facilitates remote real-time monitoring.

[0025] The following is a detailed description, with reference to the accompanying drawings, of the aquatic ecological floating nests provided by the embodiments of the present invention for attracting Baer's Pochards to breed.

[0026] See Figure 1-2 This invention provides an aquatic ecological floating nest for attracting Baer's Pochards to breed, comprising a floating platform 5, a planting trough 4, a fixed post 2, and a remote monitoring system (i.e., including a power module 8 and a monitoring probe 6). The lower section of the fixed post 2 is buried in the bottom mud layer of a designated water area, and the top of the fixed post 2 extends above the water surface. The floating platform 5 is fitted onto the fixed post 2 and can move up and down with changes in water level to always float on the water. The planting trough 4 is nested on the floating platform 5 and its bottom is submerged in water. The planting trough 4 is planted with vegetation 1 that provides shelter and nesting material for Baer's Pochards. The remote monitoring system is installed on the top of a fixed post 2 for remotely monitoring the floating nest and its surrounding environment, and is configured to remotely transmit image information to trigger an alarm when predators approach or enter.

[0027] The remote monitoring system connects to remote access terminals via mobile networks to remotely monitor floating nests and their surrounding environment, as well as predator activity. This provides intelligent management support for monitoring the breeding behavior of Baer's Pochard, monitoring nest water levels, and controlling predators. Remote access terminals can be computers or mobile apps.

[0028] Specifically, the planting trough 4 is a hollow basket structure. The fixing post 2 is inserted vertically into the bottom mud layer. The planting trough 4 is filled with soil for planting vegetation 1. Vegetation 1 consists of perennial aquatic and semi-aquatic plant species such as reeds and sedges, providing shelter for the Baer's Pochard and serving as nesting material. The height of vegetation 1 does not exceed 1.5 meters, and its coverage is not less than 70%. The weight of the soil and vegetation in the planting trough is adjusted appropriately according to the buoyancy of the floating platform to ensure that the ecological floating nest always floats on the water surface, effectively preventing the nest from being submerged.

[0029] In the above embodiment, the distance between the outer edge of the planting trough 4 and the outer edge of the floating platform 5 is 12-18cm, and should not be wider (i.e., not greater than 18cm), forming a single nest design. By deliberately reducing the area to the minimum, it is avoided from becoming a resting platform for other individuals and interfering with the incubation and reproduction of the female bird in the nest.

[0030] In the above embodiment, the planting trough 4 can be made of plastic. The planting trough 4 is nested inside the floating platform 5. The planting trough 4 is a hollow plastic basket, which allows water to permeate into the soil of the planting trough 4 and the roots of the plants 1 to penetrate into the water. Therefore, the plants 1 in the planting trough 4 can obtain water and nutrients from the water in which they are located.

[0031] In one embodiment, the floating platform 5 is an annular cylindrical shape, and the planting trough 4 is a frustum conical shape. Three fixed posts 2 are arranged in a congruent triangular array. Three sleeves 3, arranged in a congruent triangular array on a horizontal plane, are nested on the floating platform 5 outside the planting trough 4. Each sleeve 3 contains a fixed post 2, allowing the floating platform 5 to move up and down along the fixed posts 2.

[0032] It should be noted that the length of the fixing column 2 is adjusted according to the water depth at the installation location to adapt to different environments. After the lower section 2 of the fixing column is fixed to the bottom of the water, the top of the fixing column 2 is more than 50cm above the highest water level in the area to cope with rising water levels.

[0033] The dimensions of planting trough 4 and floating platform 5 are set according to actual design requirements. Based on research findings on the nesting sites of wild Baer's Pochard, a specific dimension for the planting trough and floating platform is designed as follows: the diameter of floating platform 5 is 96cm and the thickness is 15cm. Planting trough 4 is made of perforated plastic basket, with a top diameter of 60cm and a bottom diameter of 55cm.

[0034] Currently, the breeding of wild Baer's Pochard faces a severe threat from water level fluctuations, with flooding being a major cause of breeding failure. Therefore, the ecological floating nest designed in this invention can rise and fall with water level changes, always remaining afloat on the water surface, effectively preventing breeding failure due to flooding. All dimensions, specifications, and indicators of this invention are derived from eight years of continuous field surveys and practical optimization, representing the most suitable data indicators for Baer's Pochard breeding, and demonstrating a significant effect in attracting nesters and breeders in the wild.

[0035] Studies have shown that nest location and water depth significantly impact the survival of Baer's Pochard nests, as nests near the shore are more easily spotted by land-based predators, leading to nest predation. This invention, using a fixed post 2, allows artificially designed floating nests to be installed at any designated location in the water. This means the ecological floating nest can be flexibly installed in any location based on local conditions, thus avoiding factors that threaten the survival of the Baer's Pochard nest, and after eight years of field practice and continuous optimization, it has significantly improved the breeding success rate of this critically endangered bird species.

[0036] In the above embodiments, preferably, the fixing post 2 is made of stainless steel pipe, the outer surface of the fixing post 2 is coated with an anti-corrosion coating, and the lower section of the fixing post 2 is provided with a spiral anchoring structure. For example, the diameter of the fixing post 2 is 33mm, the wall thickness is 1.5mm, and the distance between two adjacent fixing posts 2 is 65cm. The sleeve 3 is a PVC pipe with a specification of DN40.

[0037] In the above embodiment, preferably, the remote monitoring system includes a monitoring probe 6 and a bracket. The bracket is mounted on one of the fixed posts 2, and the length of the fixed post 2 is greater than the length of the other fixed posts 2. The monitoring probe 6 is mounted on the top of the bracket and faces the planting trough 4. The monitoring probe has a built-in audible and visual alarm to drive away invading predators. The fixed post 2 on which the monitoring probe 6 is mounted is longer than the length of the other fixed posts 2, allowing for a longer length to obtain a suitable shooting angle.

[0038] In the above embodiment, the image information captured by the monitoring probe 6 is transmitted remotely through a mobile network, and the remote access terminal can be used to view the breeding behavior of the Baer's Pochard, as well as the environment and predator activities around the floating nest.

[0039] In one embodiment, see Figure 3 The floating ecological nest also includes intelligent weight monitoring equipment, which includes a miniature weight-sensing scale 9 and a data acquisition and transmission module. The miniature weight-sensing scale 9 is installed in the middle of the planting trough or at the bottom of the planting trough and is connected to the data acquisition and transmission module to transmit the detected weight information to the data acquisition and transmission module for monitoring weight changes and transmitting it over long distances. The data acquisition and transmission module is encapsulated on the floating platform.

[0040] Specifically, see Figure 3-4 The miniature weight-sensing scale frame 9 includes a miniature weight sensor and a scale frame 901. The scale frame 901 is a sieve-shaped circular stainless steel tray, meaning the scale frame is circular with a sieve structure at the bottom. The sieve holes are no more than 1 cm, and it is embedded in the bottom of the planting trough. The diameter of the scale frame is slightly smaller than the diameter of the planting trough corresponding to the installation location to ensure that the scale frame can be placed inside. For example, the diameter of the scale frame is 50 cm. The miniature weight sensor (brand: Zhongnuo Chuanli, model: ZNLBM-J-100KG, with waterproof treatment) is installed in the center of the bottom of the scale frame and is not shown in the figure because it is obscured by the scale frame. The data acquisition and transmission module 11 includes a pressure sensor digital conversion module, a single-chip microcomputer main controller, and an intelligent serial port data logger connected in sequence. The miniature weight sensor is connected to the input terminal of the pressure sensor digital conversion module.

[0041] Because the installation location of the miniature weight sensor is constantly submerged in water, waterproofing treatment is required, with an IP68 waterproof rating. Since the scale frame is loaded with soil and vegetation, the weight will be large after absorbing water, so a 100kg capacity specification is required, and the error will be within ±10g after waterproofing.

[0042] More specifically, the miniature weight sensor and the pressure sensor digital conversion module in the data acquisition and transmission module 11 can be connected and transmit data via a transmission line 10. It can pair and connect with the smart weight monitoring device via Bluetooth using a mobile phone, acquiring real-time recorded data and downloading all recorded weight data. The data acquisition and transmission module also includes a memory, with the microcontroller main controller connected to the memory, which can be an SD card. This memory is used to store the acquired weight data on the SD card.

[0043] In the above embodiments, the use of intelligent weight monitoring equipment can continuously and accurately record the weight changes in the planting trough and the time of these changes, thereby enabling the inference of the following reproductive parameters: the time when the female bird enters the nest to lay eggs, the rhythm of the parent birds' (entering and leaving the nest) incubation, and warming of the chicks, etc., reflecting the weight of the Baer's Pochard's eggs, the nutritional status of the parent birds and chicks, the quality of the habitat and the abundance of food, which helps to analyze the survival status of the Baer's Pochard and is of great significance for the formulation and adjustment of conservation measures.

[0044] In one embodiment, the aquatic ecological floating nest used to attract Baer's pochards for breeding also includes a power module installed on the floating platform 5. The power module provides power to the remote monitoring system and the intelligent weight monitoring equipment. Specifically, the power module supplies power to the monitoring probe 6 in the remote monitoring system and to the miniature weight sensor and data acquisition and transmission module 11 via the power cable 7.

[0045] In the above embodiment, in order to ensure that the data is not damaged and to prevent the power module from being submerged in water, a protective shell 8 is fixed on the top of the floating platform, and the data acquisition and transmission module and the power module are both installed inside the protective shell 8.

[0046] The ecological floating nest designed in this invention completely simulates the nesting site selection characteristics of wild Baer's Pochard under natural conditions, minimizing interference with its natural behavior. Furthermore, the designed remote monitoring system enables remote scientific research monitoring and emergency response.

[0047] When installing ecological floating nests based on field survey results, perennial aquatic or semi-aquatic plants such as reeds or sedges should be planted. Pre-cultivated seedlings in nutrient cups or those dug up on-site can be used, but the root system of the vegetation 1 must be intact and vigorous. Move the planted floating platform 5 to the planned installation area, then insert the fixing post 2 vertically into the bottom of the water after passing it through the sleeve 3. To ensure the floating nest can move smoothly up and down along the fixing post 2 when the water level changes, a spirit level should be used to ensure the fixing post 2 is perpendicular to the horizontal plane. After installation, fill the planting trough 4 with some dry grass as nesting material, which can effectively attract parent birds to the nest.

[0048] It should be noted that, considering the differences in soil density in different areas, the amount of soil and vegetation in the planting trough 4 should be adjusted according to the actual situation when installing the ecological floating nest on site to ensure that the ecological floating nest can support the parent birds and the nest while floating on the water surface. This invention provides a nest site structure and selective characteristics that conform to the ecological habits of the Baer's Pochard, thus having an attractive effect in wild breeding grounds lacking suitable nest sites; the aquatic ecological floating nest designed in this invention is a single nest design, which effectively solves the problems of nest density competition among the same species and mutual interference between species during the incubation and brooding period; the floating nest of this invention is far away from the land shore, effectively avoiding interference from natural enemies and ensuring the safety of the Baer's Pochard during egg laying and incubation.

[0049] By using ecological floating nests to attract Baer's Pochards, suitable nesting sites can be increased for them to build nests, lay eggs, and hatch. This can effectively solve the problem of low breeding success rate of Baer's Pochards, provide necessary guarantees for the growth of Baer's Pochard populations, and provide a technical demonstration for the protection of wild waterbirds, especially ducks, with broad ecological and social benefits.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
