“…In the Pacific Northwest, conversion of old-growth forests to plantations reduced summer stream flow by an average of 50% (Perry and Jones 2017). Preserving intact forests would provide the greatest benefit to watershed protection and clean water supply (DellaSala et al 2011). Unfortunately, the area of forest interior (defined as forest area per land area) is declining faster than the total area of forest in the United States (Riitters and Wickham 2012).…”

Forest carbon sequestration via forest preservation can be a viable climate change mitigation strategy. Here, we identify forests in the western conterminous United States with high potential carbon sequestration and low vulnerability to future drought and fire, as simulated using the Community Land Model and two high carbon emission scenario (RCP 8.5) climate models. High‐productivity, low‐vulnerability forests have the potential to sequester up to 5,450 Tg CO2 equivalent (1,485 Tg C) by 2099, which is up to 20% of the global mitigation potential previously identified for all temperate and boreal forests, or up to ~6 yr of current regional fossil fuel emissions. Additionally, these forests currently have high above‐ and belowground carbon density, high tree species richness, and a high proportion of critical habitat for endangered vertebrate species, indicating a strong potential to support biodiversity into the future and promote ecosystem resilience to climate change. We stress that some forest lands have low carbon sequestration potential but high biodiversity, underscoring the need to consider multiple criteria when designing a land preservation portfolio. Our work demonstrates how process models and ecological criteria can be used to prioritize landscape preservation for mitigating greenhouse gas emissions and preserving biodiversity in a rapidly changing climate.

“…RAs also serve as barriers against invasive species (Strittholt and Dellasala, 2001;Selva et al, 2011), preserve the natural and semi-natural habitats of many species, and their genetic resources (Loomis and Richardson, 2000). Additionally, RAs help to stabilize the climate through carbon sequestration and nutrient cycling in forested areas (Loomis and Richardson, 2000;Selva et al, 2011Selva et al, , 2015 and provide multiple ecosystem services (e.g., provision of high quality water and air, erosion control, and recreational experiences; DellaSala et al, 2011). RAs sustain potential habitat suitable for a number of species and landscape-level connectivity between natural habitats, safeguarding native biodiversity (Crist et al, 2005;van der Ree et al, 2015;D'Amico et al, 2016;Torres et al, 2016).…”

“…observations). DellaSala et al [31] have pointed out the importance of roadless areas and the relatively intact ecosystems they maintain for the conservation of threatened freshwater biodiversity and ecosystem services to humans. Basically, every land owner is responsible for creating zones where this water can be captured and allowed to percolate, but the reality shows that most owners are mainly interested in getting rid of the problem by constructing water collecting channels, and sending the water to a lower-lying neighbour, resulting in a cascading increase in quantity and velocity of surface water.…”

Soil Erosion from Agriculture and Mining: A Threat to Tropical Stream Ecosystems

2013

View full text Add to dashboard Cite

In tropical countries soil erosion is often increased due to high erodibility of geologically old and weathered soils; intensive rainfall; inappropriate soil management; removal of forest vegetation cover; and mining activities. Stream ecosystems draining agricultural or mining areas are often severely impacted by the high loads of eroded material entering the stream channel; increasing turbidity; covering instream habitat and affecting the riparian zone; and thereby modifying habitat and food web structures. The biodiversity is severely threatened by these negative effects as the aquatic and riparian fauna and flora are not adapted to cope with excessive rates of erosion and sedimentation. Eroded material may also be polluted by pesticides or heavy metals that have an aggravating effect on functions and ecosystem services. Loss of superficial material and deepening of erosion gullies impoverish the nutrient and carbon contents of the soils; and lower the water tables; causing a “lose-lose” situation for agricultural productivity and environmental integrity. Several examples show how to interrupt this vicious cycle by integrated catchment management and by combining “green” and “hard” engineering for habitat restoration. In this review; we summarize current findings on this issue from tropical countries with a focus on case studies from Suriname and Brazil
