Overview of the study system. Panel A shows a regional map with the locations of the 23 study sites marked in red, with an inset of the national map in the top-left with the study area in southwestern Ethiopia marked with a red square. The photos below the regional map illustrate B) herbivory (coffee leaf skeletonizer; Leucoplema dohertyi; photo by Ayco Tack) and examples of the local C) bird (common bulbul Pycnonotus barbatus; photo by Kristoffer Hylander) and D) bat community (Egyptian tomb bat Taphozous perforatus, photo by Jens Rydell).

The relationship between coffee yield and a) bird species richness, b) bat species richness, c) bird community composition (axis 1 of an NMDS ordination) and d) bat community composition (axis 1 of an NMDS ordination) across 23 sites in southwestern Ethiopia. Shown are regression slopes with 95% confidence intervals from a GAM model. Solid lines represent a significant relationship (P < 0.05) and dashed lines represent a non-significant relationship (P > 0.05). For statistical details, see Table S5.

Fig. 1. Overview on study design and hypothesis. A) Across three regions of Germany, land-use reduction experiments were established. Depicted for the Schwäbische Alb region, black squares show location of experiments, light green indicates grasslands, and dark green forests (with white being agriculture and settlements). B) Per region, land use at 15 grasslands each (total n = 45) was experimentally reduced within a matrix that also comprised the control plot. C, D) We expected that the experimental reduction of land use increases the abundance (and also diversity) of arthropods and that the increase is larger in less-intensively used grasslands. Maps are from OpenStreetMap (OpenStreetMap Contributors 2022) and arthropod silhouettes from phylopic.org (available under a CC0 1.0 license).

Fig. 3. Treatment effects of experimental land-use reduction on arthropod abundance A) decreased in both sampling years when reduction plots were in a more frequently mown matrix. In turn, treatment effects became larger B) when the matrix had been fertilized more. One year after establishment of the experiment, C) treatment effects on abundance increased with mowing height of the reduced land-use plot; after three years, D) treatment effects were larger if reduced land-use and control plot had not been mown at the same day. Points are partial residuals of log-response ratios between treatment and control plots. Regression lines (95 % CI as shaded polygons) indicate the predictions of averaged linear mixed-effects models. Dashed horizontal lines mark null. Mowing and fertilization are averaged over the respective three years before sampling. The x-axis in B) is on a square-root scale.

🌾 New in #BAAE:

Reduction of land use increases invertebrate abundance in grasslands.

Cutting mowing intensity boosted invertebrate numbers by up to 99% over 3 years, showing how land-use reduction supports insects & ecosystem functions. 🌿

Geographical distribution of observations from studies included in the final analysis. Circle size is scaled for visualization purposes to improve visibility of overlapping data points, and does not encode any quantitive information. The center of each circle corresponds to the coordinates of the reseach area of the included studies.

Probabilities of observing an increase or no change in biodiversity upon conservation of extensively managed grasslands, and of observing an increase in biodiversity after restoration of previously abandoned or intensively used agriculturally marginal grasslands. Numbers indicate sample sizes. Raw data are overlaid as jittered points to show the distribution of observed outcomes that informed the model.

🌿🪶 New Review in #BAAE: Abandonment & intensification impact biodiversity in marginal grasslands.

Across 174 European studies, both pathways reduced diversity — while restoration & extensive management help recover ecological value. 🌾
