“…We used the analysis tool of Conefor 2.6 (http://www.conefor.org, accessed on 15 March 2021) to conduct connectivity analysis on the basis of habitat patches in 1975,1980,1985,1990,1995,2000,2005,2010, 2015, and 2020. Conefor 2.6 is a simple program that quantifies the importance of habitat patches for maintaining landscape connectivity through graph structures and habitat availability indices [7]. A habitat patch file, habitat connectivity file, ecological resistance surface, and maximum dispersal distance of species are required to run this program.…”

“…Coastal wetlands in China provide important stopover sites for migratory shorebirds along the East Asian-Australasian Flyway (EAAF) migratory route [4,5]. However, land-use change has affected the size and structure of available habitat, as well as ecosystem functions [6,7], and this has implications for habitat connectivity. The effects of land-use change on coastal habitat connectivity have not yet been clarified.…”

Coastal wetlands form a transition zone between terrestrial and marine environments and provide important ecosystem services. Land-use change in the coastal zone has a substantial effect on habitat connectivity and biodiversity. However, few studies have characterized the effects of land-use change on coastal habitat connectivity. We conducted remote sensing analysis, modeling with the Integrated Valuation of Ecosystem Services and Trade-offs model, geospatial analysis, and habitat connectivity analysis to evaluate historical spatiotemporal changes in the habitat quality and habitat connectivity of migratory shorebirds in the Yellow River Delta, which is an important stopover site along the East Asian–Australasian Flyway migratory route. Several high- and medium-quality areas have been converted to industrial mining and mariculture sites because of land reclamation. The probability of connectivity decreased by −66.7% between 1975 and 2020. Approximately 71.0%, 11.6%, and 5.8% of patches with high importance have been converted to non-habitat patches, habitat patches with medium importance, and habitat patches with low importance, respectively; approximately 58.9% and 11.7% of the patches with medium importance have been converted to non-habitat patches and habitat patches with low importance, respectively. The total priority conservation area was 389.4 km2, and 125.0 km2 (32.1%) of this area remains unprotected; these unprotected areas are mainly distributed in the northwestern and eastern parts of the Yellow River Delta. We recommend that the boundary of the Yellow River Delta National Nature Reserve be expanded to incorporate these unprotected areas.

“…The Yancheng Coastal Wetland is located at the core of the newly established UNESCO World Heritage Site (China Yellow Sea Bohai Bay Coastal Migratory Bird Protection Area (Phase I)) in 2019, which attributes to the ecological effects of the wetland on the microbe, plants, aquatic animal, and rare waterbirds [24,25]. This wetland attracts tens of thousands of waterfowl every year for wintering, breeding, and habitat, which include endangered and vulnerable species such as the red-crowned cranes (Grus japonensis), oriental white stork (Ciconia boyciana), spoon billed snipe (Eurynorhynchus pygmaus), and sander seagull (Larus saundersi) [26,27].…”

The wetland played a crucial role in producing oxygen and purifying the air, so the conservation projects were essential in response to natural and perceived destruction. The farmland restoration project was utilized to repair the southern buffer zone of Jiangsu Yancheng Wetland National Nature Reserve for Rare Birds on the investigation and analysis of migratory birds, soil fauna and crops. In this paper, the five different crops of colza oil, mustard, Chinese cabbage, wheat, barley were planted in the restoration plots, which was eaten by migratory birds overwinter resulting to the low yield of crops. The species and biomass of soil fauna in non-winter (7 species and 98 soil fauna) were more than that in winter (6 species and 54 soil fauna), and the results of restoration plots was more than that in control. The variety and number of migratory birds had a significant improvement (18 species and 164231 migratory birds), which was owed to different crops and soil fauna. This study found that farmland restoration project could significantly improve the ecological environment of wetland, enrich the biodiversity and attract more migratory birds for inhabit.

“…Water birds are an important component of natural wetland systems, and they play a key role in sustaining wetland biodiversity. Water bird conservation has become one of the important elements of biodiversity conservation in wetland ecosystems worldwide [ 1 , 2 , 3 ]. Disseminating bird knowledge to the public and promoting public participation are critical to bird conservation, especially rare and endangered birds.…”

Enabling the public to easily recognize water birds has a positive effect on wetland bird conservation. However, classifying water birds requires advanced ornithological knowledge, which makes it very difficult for the public to recognize water bird species in daily life. To break the knowledge barrier of water bird recognition for the public, we construct a water bird recognition system (Eyebirds) by using deep learning, which is implemented as a smartphone app. Eyebirds consists of three main modules: (1) a water bird image dataset; (2) an attention mechanism-based deep convolution neural network for water bird recognition (AM-CNN); (3) an app for smartphone users. The waterbird image dataset currently covers 48 families, 203 genera and 548 species of water birds worldwide, which is used to train our water bird recognition model. The AM-CNN model employs attention mechanism to enhance the shallow features of bird images for boosting image classification performance. Experimental results on the North American bird dataset (CUB200-2011) show that the AM-CNN model achieves an average classification accuracy of 85%. On our self-built water bird image dataset, the AM-CNN model also works well with classification accuracies of 94.0%, 93.6% and 86.4% at three levels: family, genus and species, respectively. The user-side app is a WeChat applet deployed in smartphones. With the app, users can easily recognize water birds in expeditions, camping, sightseeing, or even daily life. In summary, our system can bring not only fun, but also water bird knowledge to the public, thus inspiring their interests and further promoting their participation in bird ecological conservation.
