Abstract

In this study we analyzed if characteristic calcareous grassland species persist in forest habitats after land use change. Furthermore, we investigated whether the current distribution of such species is related to historical land use of the mid-19th century. Current distributions of nine calcareous grassland species were recorded in a region of Upper Franconia, Germany. Historical (up to 1850) and current land-use data were analyzed using historical maps and aerial photographs. To study the effects of historical land use in current species distributions, we used Generalized Estimating Equations (GEE) and ANOVA, accounting for spatial autocorrelation. Variance partitioning was applied to separate the influence of historical versus current land use. On average 26% of the recorded grassland species occurrences are located in sub-optimal forest habitats. Grassland populations are likely to persist in forest for at least 50 years. Even though current land use explains a higher proportion of the variation in species distribution than historical land use alone, model fit could be significantly improved (P < 0.001) considering the historical component. We conclude that consideration of historical land use is essential to understand the current grassland species distributions and may be of general importance for perennial species of temperate grasslands. In addition, historical legacy has far-reaching implications for conservation biology in terms of realistic assessments of species threat status in present landscapes.

Electronic Supplementary Material 2Regression coefficients derived from generalized estimating equations (GEE). Calculation is based on a 70 × 70 m grid. The response is given by the presence/absence of calcareous grassland species while current (2005) and historical (1850) land use categories serve as predictors (binary coded). The first row of each species (2005) shows results of current land use categories, while the second row (1850) relates to historical land use categories. Positive signs (+) indicate species abundance on the respective land use categories, considering current land use. Negative signs (−) indicate species absence. Significance levels show the strength of the relation. The lower the significance level (* – P < 0.05, ** – P < 0.01, *** – P < 0.001), the higher is the probability of finding a species in the corresponding land use type. Considering the results of 1850, species occurrence in relation to historical land use types are displayed (DOC 230 kb)
