Understanding the effects of traditional livestock grazing abandonment on the
ability of mountain grasslands to sustain multiple ecosystem functions (ecosystem
multifunctionality; EMF) is crucial for implementing policies that promote grasslands
conservation and the delivery of multiple ecosystem services. In this study, we evaluated
the effect of short- and long-term transhumant sheep abandonment on EMF through a
grazing exclusion experiment in a grassland of the Cantabrian Mountains range (NW
Spain), where transhumant sheep flocks graze in summer. We considered four key
ecosystem functions, derived from vegetation and soil functional indicators measured
in the field: (A) biodiversity function, evaluated from total plant species evenness,
diversity and richness indicators; (B) forage production function, evaluated from cover
and richness of perennial and annual herbaceous species indicators; (C) carbon
sequestration function, evaluated from woody species cover and soil organic carbon
indicators; and (D) soil fertility function, evaluated from NH4C-N, NO3-N, P and K
content in the soil. The EMF index was calculated by integrating the four standardized
ecosystem functions through an averaging approach. Based on linear mixed modeling
we found that grazing exclusion induced significant shifts in the considered individual
ecosystem functions and also on EMF. Long-term livestock exclusion significantly
hindered biodiversity and forage production functions, but enhanced the carbon
sequestration function. Conversely, the soil fertility function was negatively affected by
both short- and long-term grazing exclusion. Altogether, grazing exclusion significantly
decreased overall EMF, especially in long-term livestock exclusion areas, while the
decline in EMF in short-term exclusions with respect to grazed areas was marginally
significant. The results of this study support the sustainability of traditional transhumance
livestock grazing for promoting the conservation of grasslands and their ecosystem
function in mountain regions.
