“…The second key issue was the consideration of model parameters. Based on the relevant literature [3,11,24,27,[38][39][40][41][42] and the expert knowledge, we assigned the maximum stress distance and weight of each threat factor, and assigned the sensitivity of various habitat types to the threat factors (Tables 1 and 2). To facilitate the comparisons of habitat quality changes, and using the equal interval method, we divided the habitat quality index into five grades: V (0 to 0.2), IV (0.2 to 0.4), III (0.4 to 0.6), II (0.6 to 0.8), and I (0.8 to 1).…”

Habitat quality is an important indicator for evaluating the biodiversity provided by ecosystem. Estimating and scenario-simulating the dynamic evolution and future development trends of habitat quality under the influence of land-use change is significant in regional biodiversity conservation, formulating land-use planning, and maintaining the ecological environmental sustainability. In this article, we included the Huaihe River Economic Belt as the area of study because of its vital location in China and applied the CA–Markov and InVEST models to analyze the spatio-temporal evolution of habitat quality and to simulate the future development trends of habitat quality under three different land-use scenarios: fast urban growth scenario, farmland conservation-oriented scenario, and ecological conservation-oriented scenario. The results showed that the land-use change in the Huaihe River Economic Belt was mostly represented by the continuous increase of the built-up area, whereas other land types all declined in area from 1995 to 2015. The land-use changes under these three abovementioned alternative future scenarios with different development orientations were considerably different. The built-up area has been shown to expand rapidly to occupy other land types on a large scale under the fast urban growth scenario. Urban land increased slightly and a large area of rural residential land would be converted into farmland under the farmland conservation-oriented scenario. The built-up area and farmland might decrease while woodland, grassland and water would increase in extent of areas under the ecological conservation-oriented scenario. Habitat quality has been shown to be generally poor, continuing to decline from 1995 to 2015, while its spatial distribution was higher in the southwest and northeast areas and lower in the central regions. The future habitat quality would display a downward trend under the fast urban growth and farmland conservation-oriented scenarios with a further deterioration of the ecological environment, while the ecological conservation-oriented scenario predicted the converse trend that the ecological environment would be improved productively. This study may be useful for understanding the impact of land-use dynamics on biodiversity. The research results can provide a scientific basis for the decision-makers to formulate biodiversity conservation and land management policies.

“…This finding was similar to that in other studies. For example, the total area of historical forests in the southern part of Seoul in 2015 decreased by 35% compared to the value in 1972 (Han et al 2019). During the 2009-2018 period, we found that the area of historical forests in Guiyang declined dramatically.…”

“…First, existing studies have mainly concentrated on the impact of landscape patterns based on the current situation of urban land use (Huang et al 2013;Williams and Winfree 2013;Yang et al 2020). Few studies have considered the association between temporal changes in urban land use and the formation process of historical forest patches in a city (Han et al 2019). Understanding the historical information of remaining forests during the process of urbanization in a city is beneficial for the development of more effective conservation activities based on historical trends and laws (Ramalho and Hobbs 2012).…”

Background: Remaining historical forests are crucial for maintaining biodiversity in urban areas. However, the integrity and stability of historical forests are affected by land use/cover change in various ways. A better understanding of these impacts can help guide targeted conservation. Methods: In this study, we estimated the loss of forestlands and levels of threats and analysed the importance of critical areas for historical forests in the built-up area of a rapidly urbanizing city—Guiyang, China. Results and Conclusions: The results showed that 1988.46 ha of historical forestlands was transformed into other land use/cover types. The number of patches smaller than 10 ha increased by 51% from 1976 to 2018. The lands of 36 historical forest patches were completely transformed into other land use/cover types during the past 42 years. The mean value of the threat index of all the historical forest patches increased by 33% compared to the baseline year. Core and bridge areas regarded as key nodes and links for the connectivity of forest networks decreased in area by 632.34 and 331.92 ha, respectively. Most of the critical areas with high importance values for connectivity were located in the central part of the city. They were severely threatened by the surrounding areas, having high threat index values. Based on these findings, we recommend that effective measures be implemented to control the further loss of historical forests and increase the connectivity and buffering capacity of the remaining forests by planting trees in some key locations.

“…A review of all publications using the InVEST software showed that these threats have not been considered in other studies so far. In comparison to other studies of habitat quality modeling in the context of urban threats [29,[32][33][34][35][36], this is the first study that has considered the combination of threat impacts from built-up areas, road networks, and water pollution, as well as utilizing a high-resolution habitat suitability input. It is also the first application of the model to a river corridor.…”

While for most of a landscape, urbanization leads to a significant habitat loss, rivers in urban areas are usually maintained or developed for their drainage function. Rivers are often the most important biophysical and ecological connection of cities with their surrounding ecosystems, although usually heavily altered due to urban impacts. For the conservation of urban rivers as ecological corridors, it is important to assess the impact of typical urban threats on habitat quality. In this study, we used the InVEST (Integrated Valuation of Environmental Services and Trade-offs) habitat quality model to assess the individual and combined impacts of built-up areas, first- and second-order road and water pollution from urban drainage, and wastewater discharge on habitat quality within a 200 m wide river corridor. The Pochote River in León, Nicaragua, was used as a case study. Our results show the spatial distribution and magnitude of the individual threat impacts, as well as the respective contribution of each threat to the overall impact of urbanization on the habitat quality within the river corridor. While close to the city center, all threats almost equally contributed to severe habitat degradation, while further downstream, an individual threat influence became more distinct with only water pollution having a consistent negative impact. We concluded that the InVEST habitat quality model can be used to assess the impact of typical urban threats on habitat quality in river corridors at a high spatial resolution. The results can help to improve urban planning and development to improve habitat conservation along urban rivers.
