Functional diversity enhances tree growth and reduces herbivory damage in secondary broadleaf forests, but does not influence resilience to drought

Abstract Since the mid‐20th Century, Europe has experienced an unprecedented forest expansion associated with abandonment of rural landscapes. Secondary forests may provide relevant ecosystem services such as landscape defragmentation, biodiversity conservation, control hydrological cycling and carbon sequestration. benefit from legacies former agricultural land use, exhibit enhanced growth. Moreover, they differ long‐established in terms tree species composition diversity, community been less modified by succession or management. However, we lack evidence whether effects use on diversity also result differences response secondary to biotic abiotic disturbances. We aimed evaluate taxonomic functional their temperate broadleaf drought herbivory damage. For this aim, compared beech Fagus sylvatica established after 1950 abandoned pastures (pre‐1950) forests. calculated indices determined mean growth two events (1991, 2006), insect marginally differed richness but exhibited a significantly higher Shannon index evenness.

This principle should be applied management well expanding does seem ameliorate drought, highlighting need other silvicultural practices address environmental challenge.

Interventions for resilient nature‐based solutions: An ecological perspective

Abstract Nature‐based solutions (NbS) have emerged at the science, policy and practitioner interface to address environmental challenges facing society. NbS involve people working with nature protect, restore or manage ecosystems. Yet vary extent they support biological diversity which has implications for ecological resilience. We reviewed how resilience been conceptualised in literature.

Avian species functional diversity and habitat use: The role of forest structural attributes and tree diversity in the Midlands Mistbelt Forests of KwaZulu‐Natal, South Africa

Ecology and Evolution, Journal Year: 2023, Volume and Issue: 13(9)

Published: Aug. 31, 2023

Forest transformation has major impacts on biodiversity and ecosystem functioning. Identifying the influence of forest habitat structure composition avian functional communities is important for conserving managing systems. This study investigated effect characteristics bird species community structure, use diversity in 14 Mistbelt patches Midlands KwaZulu-Natal South Africa. We surveyed using point counts. quantified each patch three indices: richness, evenness divergence. further assessed species-specific responses by focussing specialists, orange ground-thrush Geokichla gurneyi, canary Crithagra scotops Cape parrot Poicephalus robustus. found that forest-specialist to tree differed. Also, structural complexity, canopy cover richness were main better at explaining microhabitat diversity. with relatively high complexity had higher richness. Different influenced specialists. Tree C. G. gurneyi positively, while P. robustus responded negatively Our showed site-scale are should be maintained conserve

Forest-clearing to create early-successional habitats: Questionable benefits, significant costs

Frontiers in Forests and Global Change, Journal Year: 2023, Volume and Issue: 5

Published: Jan. 9, 2023

A campaign is underway to clear established forests and expand early-successional habitats—also called young forest, pre-forest, early seral, or open habitats—with the intention of benefitting specific species. Coordinated by federal state wildlife agencies, funded with public money, land managers work closely hunting forestry interests, conservation organizations, trusts, private landowners toward this goal. While forest-clearing has become a major focus in Northeast Upper Great Lakes regions U.S., far less attention given protecting recovering old-forest ecosystems, dominant cover these before European settlement. Herein we provide discussion habitat programs policies terms their origins, context historical baselines, respect species’ ranges abundance, as they relate carbon accumulation ecosystem integrity. Taken together, face urgent global crises climate, biodiversity, human health, conclude that forest management must be reevaluated balance prioritization funding strong lasting protection for old-growth mature forests, and, going forward, ensure more robust, unbiased, ongoing monitoring evaluation.
