Habitat quality for many wildlife populations has a spatial component related to the arrangement of habitat elements across large geographic areas. With remote sensing and GIS technology, this paper presents an approach to calculate Habitat Suitability Index (HSI) for Giant Pandas to evaluate the habitat quality. In this paper, a buffer of a given distance (30 km or more) to the Giant Panda distribution area estimated in three national surveys (1974, 1989 and 2002), which is located in Sichuan, Gansu and Shanxi provinces in western China, was used as the study area. In order to study different species group’s habitat quality, the study area is divided into five parts: the Qinling mountain systems, located in the southeast in Shanxi province, the Minshan mountain systems, located in the south in Gansu province and northwest in Sichuan province, the Qionglai mountain systems, the Xiangling mountain systems and the Liangshan mountain systems, located in the west of Sichuan province, conforming to the five big Giant Panda species groups. Three physical environmental factors (elevation, slope and aspect), one ecological factor (vegetation distribution) and several human-influence factors (distances to highways, general roads, inhabitants and rural areas) are selected as the influence factors to calculate HSI. Each factor was reclassified by grid-cell (30 × 30 m per cell) to the suitability index scale from 0 to 1 based on habitat affinities before final calculation. After analyzing the HSI values on the most Giant Panda distribution area, 0.0144 was considered as the threshold habitat quality. Then, HSI was calculated for five mountain systems for three periods conforming to three national surveys (1974, 1989 and 2002). Several benefits to the approach can be highlighted. Firstly, HSI can be used as the standard to evaluate the quality of Giant Panda habitat. Secondly, by using HSI maps from 1974, 1989 and 2002, we can see that the Giant Panda habitat was the largest in 1974, and was then reduced much before 1989. However, by 2002, it had recovered to some extent, which conforms to the habitat data from the three national surveys. Thirdly, the habitat changes in the five mountain systems examined in the study are different. Finally, nature reserves play an important role in the protection of Giant Panda habitat; there are more suitable habitats in nature reserves than non-protected areas.

In 13 forest reserves situated in southern Poland, 68 study plots were established in two regions: the Jurrasic Upland and the Silesian Upland. In these plots, size 10 m × 10 m divided into 100 subplots 1m² each and randomly placed in various forest communities, percentage cover of all species in ground layer was recorded. Relationships between highly invasive alien plant species, Asiatic small balsam Impatiens parviflora DC., and indigenous species, was estimated using various indexes of species richness and diversity. They were: Hill’s numbers (N₀, N₁, N₂), ShannonWiener’s index at the level of a subplot, alpha diversity (species richness within sites), and beta diversity (species richness among sites) at level of a study plot. The subplots with a presence of I. parviflora were compared with those where only native resident species occurred. The study has shown that subplots with the occurrence of I. parviflora are characterized by higher species richness and diversity of native plants independently on vegetation type. The frequency of I. parviflora was negatively correlated with beta diversity of study plots but there was no association with values of alpha diversity. In oak forest, alder carrs and floodplain forests the negative correlation between percent cover of I. parviflora and species richness, as well as cover of the herb layer was observed. The percent cover of I. parviflora was positively correlated with number of native species in beech forest and with their total cover in mixed coniferous forests. However, in natural well-preserved forest phytocoenoses I. parviflora avoids patches characterized by high cover of ground layer species and colonizes empty sites as an additional element of a community.

Understanding the factors affecting the species richness of alien and native plant is a key issue for predicting the spread of alien species and protecting rare and endangered native species in nature reserves. To investigate the factors affecting alien and native species richness in temperate nature reserves of China, we used a database of 25 nature reserves in Shandong Province of northern China, and studied the relationship of alien and native plant species richness with climatic and anthropogenic factors, as well as area and elevation range. We found that most of the nature reserves in Shandong Province have been invaded by alien plant species. The distribution of alien and native species responds to the same climatic factors, and temperature and precipitation exert strong effects on both groups. Alien and native plant species richness are positively correlated. Human activity is more effective for explaining richness of alien than for native species. Simultaneously, human activity has stronger effects on alien herbaceous than on alien woody plants. Our results suggest that native species richness is mainly explained by climatic factors, whereas alien species richness is mainly explained by climatic factors and human activity together.

Occurrence of rare and protected plant species is regarded as a strong argument for creating a protected area. It is therefore especially important to know whether rare and protected species are reliable indicators of abundance of other, more common, unprotected species. We analysed co-occurrence of protected and rare species with other xerothermic plant species in calcareous xeric grassland in Western Poland. In the years 2005–2006, on 62 plots (25 m² each) we identified vascular plants on a 60 km² area in the Odra R. Valley and its smaller tributaries valleys. Legally protected species appeared not to be better indicators of xerothermic species richness than non-protected species. The rarest species (Anthericum liliago L., Carex supina Willd. ex Wahlenb. and Stipa borysthenica Klokov ex Prok.) were significantly less useful indicators of xerothermic species richness than other rare and common species. These results let us conclude that designing a network of protected areas on the basis of rare and protected species may result that some common species, biodiversity hotspots or well developed phytocenoses will be ignored.
