diversity is globally threatened by anthropogenic land use including
management and modification of the natural environment. At regional and
local scales, numerous studies world-wide have examined land use and its
effects on plant diversity, but evidence for declining species
diversity is mixed. This is because, first, land use comes in many
variations, hampering comparisons of studies. Second, land use directly
affects the environment, but indirect effects extend beyond the
boundaries of the land in use. Third, land-use effects greatly depend on
the environmental, historical and socio-economic context.
evaluate the generality and variation of studies’ findings about
land-use effects, we undertook a quantitative synthesis using
- Using 572 effect sizes from 375
studies distributed globally relating to 11 classes of land use, we
found that direct and indirect effects of land use on plant diversity
(measured as species richness) are variable and can lead to both local
decreases and increases. Further, we found evidence (best AIC model)
that land-use-specific covariables mostly determine effect-size
variation and that in general land-use effects differ between biomes.
- Synthesis and applications.
This extensive synthesis provides the most comprehensive and
quantitative overview to date about the effects of the most widespread
and relevant land-use options on plant diversity and their covariables.
We found important covariables of specific land-use classes but little
evidence that land-use effects can be generally explained by their
environmental and socio-economic context. We also found a strong
regional bias in the number of studies (i.e. more studies from Europe
and North America) and highlight the need for an overarching and
consistent land-use classification scheme. Thereby, our study provides a
new vantage point for future research directions.
