In parallel, NDVI changes were assessed on satellite images acquired during the two periods. In addition, two high-resolution orthophotos from 2007 and 2023 were used to classify land cover types into three classes: bare soil, grass and woody vegetation, and to assess changes in land cover types within a 20-m buffer around the plots.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>We assessed differences between vegetation types and the type of process detected for taxonomic and functional turnover, NDVI distances and land cover changes.

Interaction between these components regulates a wide range of ecosystem functions. However, little is known about biocrusts associated with different vascular plant species, and understanding the interactions between them remains a challenge.

Different vascular plant species hosted different biocrust assemblages, which were partially explained by plant canopy architecture traits. However, relevant vascular plant traits differed in relation to biocrust composition or total cover. Whereas loose, large, and inverted cone-shaped canopies provided a canopy service for the development of biocrust cover, vascular plant height was strongly correlated to a gradient in biocrust composition from ruderal to slow-colonizer species.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>Our study demonstrates that vascular plants greatly contribute to increasing biocrust heterogeneity, evidencing that biocrust-plant interaction should be accounted for in the assessment of dryland ecology and management.
