Kan biologisk mångfald ökas i ett avsatt skogsområde? por Forsmark, Linnea

“…The inventory of nature conservation values reveals areas with high biodiversity, but to improve biodiversity prerequisites to a higher level, I have planned management actions like 1) make some stands more open, create sunlit stems, reduce the competition between trees, 2) create gaps, to enhance heterogeneity and create new areas where flora and tree seedlings can establish, 3) releasing of pioneer trees, to increase stem widths and also create sunlit stems, 4) precommercial thinning to reduce the understory of spruce, 5) prescribed burning to create a primary succession, create burned wood and lower tree-vitality, and also reduce the ground vegetation, 6) create dead wood or dying trees by tipping, cutting or scarify trees. …”

Structural heterogeneity of wildflower strips enhances fructose feeding in parasitoids por Mockford, Alice, Westbury, Duncan B., Ashbrook, Kate, Urbaneja, Alberto, Tena, Alejandro

“…Using orange orchards as a model system, three experimental alleyway management treatments were investigated: a control treatment where naturally occurring vegetation in the alleyways between rows of trees was managed under standard farm practice; a standard management wildflower treatment in which sown wildflower strips in alleyways were managed by cutting once a year; and an active management wildflower treatment, in which the wildflower strips in alleyways was managed by cutting three times a year. …”
