Ecology and Management of Oak Forest Ecosystems

Oak forests represent foundational components of many temperate and Mediterranean landscapes, supporting high levels of biodiversity, regulating hydrological cycles and storing considerable amounts of carbon. Their complex structure arises from a mosaic of successional stages, underpinned by interactions among disturbance regimes (fire, windthrow, drought), soil conditions and biotic factors such as herbivory and pathogen outbreaks. Oaks (Quercus spp.) often dominate mature canopies but exhibit variable recruitment success, leading to shifts towards mesophytic or invasive species under altered disturbance or climate regimes. Management goals balance the maintenance of oak dominance, wildlife habitat provision and timber production with ecosystem resilience to stressors including drought, pests and land-use change. Silvicultural interventions—such as shelterwood harvests, midstory removal and underplanting—are used to favour light-demanding oak regeneration, while adaptive monitoring strategies (for example risk mapping of decline) inform early responses to emerging threats. Restoration of degraded oak systems may involve conversion of exotic plantations to native hardwood stands, control of competing vegetation and exclusion of herbivores. Recent advances emphasise landscape-scale planning, integration of remote sensing and citizen engagement, and the need for dynamic indicators of successional trajectories to guide long-term conservation and sustainable use.

Ecology and Management of Oak Forest Ecosystems publication trend

The graph below shows the total number of articles in ecology and management of oak forest ecosystems across all publications each year (not limited to Nature Index journals).

Technical terms

Successional trajectory: The directional change in species composition and structure of a forest over time following disturbance.

Shelterwood: A silvicultural system in which selected canopy trees are retained temporarily to guide the establishment of new seedlings.

Basal area: The total cross-sectional area of tree stems per unit ground area, used as a measure of stand density.

Mesophication: The process by which forests shift towards dominance by shade-tolerant, moisture-loving species, often following fire suppression.
