Abstract:
... Landslides and gullies are two common manifestations of land degradation in the densely populated Colombian Andes. In these unstable areas, further mass movements pose a serious threat to local populations and cause off‐site environmental damage through sedimentation, pollution, and increased flooding. A novel approach for restoring severely eroded slopes combines the use of stabilization structur ...
biodiversity; case studies; ecological restoration; forests; habitats; landscape ecology; landscapes
Abstract:
... The effectiveness of ecological restoration actions toward biodiversity conservation depends on both local and landscape constraints. Extensive information on local constraints is already available, but few studies consider the landscape context when planning restoration actions. We propose a multiscale framework based on the landscape attributes of habitat amount and connectivity to infer landsca ...

Abstract:
... Given that 29% of seabird species are threatened with extinction, protecting seabird colonies on offshore islands is a global conservation priority. Seabirds are vulnerable to non‐native predator invasions, which reduce or eliminate colonies. Accordingly, conservation efforts have focused on predator eradication. However, affected populations are often left to passively recover following eradicati ...
... Rarely assessed in the success of ecological restoration projects is the maintenance of genetic variation in restored populations and, critically, their offspring. A founding population sourced from a limited genetic pool of nonlocal provenance seed can result in genetic bottlenecking and inbreeding, potentially reducing future population resilience and restoration success. We used microsatellite ...
... Native shrublands dominate the Great Basin of western of North America, and most of these communities are at moderate or high risk of loss from non-native grass invasion and woodland expansion. Landscape-scale management based on differences in ecological resistance and resilience of shrublands can reduce these risks. We demonstrate this approach with an example that focuses on maintenance of sage ...
... Successful restoration of ephemeral wetlands worldwide is particularly challenging, given the often‐precise relationship between hydrological features and plant community dynamics. Using a long‐term experiment in vernal pool restoration, we compare hydrological and vegetative characteristics of constructed pools with those of adjacent, naturally occurring reference pools. Although constructed and ...
... Ecological restoration typically seeks to shift species composition toward that of existing reference sites. Yet, comparing the assemblages in restored and reference habitats assumes that similarity to the reference habitat is the optimal outcome of restoration and does not provide a perspective on regionally rare off-site species. When no such reference assemblages of species exist, an accurate a ...

Here, we present an innovative approach based on principal response curves (PRC) and species classification according to their preferential habitats to monitor changes in community composition. Following large‐scale restoration of a cut‐over peatland, vegetation was surveyed biannually over 8 years. We evalua ...
... Multiscale spatial patterns of forest reference conditions offer insight on how historical and environmental processes have influenced forest stand dynamics. Yet, spatial information is often either unavailable or partial, because many studies provide nonspatial reference condition information, whereas others only report the local (i.e. observed at plot extent) spatial arrangement of trees. Howeve ...
... Sponges are dominant components of coral reef ecosystems, often exceeding reef-building corals in abundance. Large sponges, often more than 1 m in diameter, may be hundreds to thousands of years old. When damaged or dislodged, large sponges usually die because they are unable to reattach to the reef substratum. Because suitable methods for reattaching dislodged sponges are lacking, they are typica ...

... Vegetation recovery in severely disturbed alpine ecosystems can be accelerated through active restoration measures. This study evaluated the short‐term effects of two restoration treatments, planting of propagated native Salix (willow) shrubs in three different densities (1, 2.5, and 4 plants/m²) and seeding of the native grass Festuca ovina (sheep fescue), in a disturbed alpine heathland. We eval ...
... Restoration practices incorporating timber harvest (e.g. to remove undesirable species or reduce tree densities) may generate unmerchantable wood debris that is piled and burned for fuel reduction. Slash pile burns are common in longleaf pine ecosystem restoration that involves hardwood removal before reintroduction of frequent prescribed fire. In this context, long‐lasting effects of slash pile b ...
... Many studies have demonstrated that reduced light availability, which can be manipulated at local scales by planting or seeding canopy species, can curtail the growth of invasive species and promote the growth of native species. Species differences in functional traits, such as light use and stress tolerance, may be used to determine how native and invasive species will respond to these resource m ...
... Efforts to eradicate invasive plants in restorations can unintentionally create conditions that favor reinvasion over the establishment of desired species, especially when remnant invasive propagules persist. Reducing resources needed by the invader for seedling establishment, however, may be an effective strategy to prevent reinvasion. Propagules of Phalaris arundinacea persist after removal from ...
... Species native to ecotones are often overlooked in restoration efforts despite the increasing rarity of ecotone habitat. In fragmented, fire-suppressed landscapes, true ecotone may no longer exist. Restoration biologists interested in reintroducing ecotone species must decide whether to plant them in historic ecotones maintained by manual thinning or whether to opt for discrete restoration areas t ...

The objective of this study was to direct soil microbial biomass (SMB) size and activity with organic amendments. These amendments were applied to the soil at different amendment locations (incorporated versus surface-applied) and amounts (none, light, and heavy) in a 2 × 3 facto ...
... In most drylands, biological soil crusts (biocrusts), an assemblage of lichens, bryophytes, fungi, green algae, and cyanobacteria, are critical to healthy ecosystem function. However, they are extremely sensitive to disturbance and attempts to facilitate their recovery have had variable success. In this study, we applied soil amendments designed to improve soil surface stability and accelerate bio ...

Abstract:
... Forests dominated by oak, beech, hornbeam, and boreal conifers are characterized by resource pulses. Contemporary eastern U.S. oak forests may exhibit dramatic resource pulses in part because of the loss of American chestnut, which comprised 25–50% of the canopy throughout its range. Chestnut loss may have reduced mast resources for wildlife. A newly developed, blight‐resistant hybrid makes reintr ...
... We evaluated the restoration of native plant assemblages by topsoil translocation in the Hunter Valley, south‐east Australia. Species' responses were characterized by defining nine plant functional types (PFTs) based on combinations of four response mechanisms (seed bank persistence, germination cues, resprouting mechanisms, and longevity) through which species were predicted to persist or decline ...
... Ants are effective at moving seeds toward their nests, something that may benefit the seeds. We evaluated whether seed movements that may be useful for the rehabilitation of degraded pastures in Colombia can be enhanced by local ants. An artificial aril was prepared and then evaluated in six open cattle pasture farms. Twenty paper disks (each holding seeds with an artificial aril, honey, tuna oil, ...

Abstract:
... A considerable number of institutions offer courses in restoration ecology and its application, ecological restoration. We quantified the scope and structure of introductory restoration courses at 67 post‐secondary institutions by reviewing institutional course catalogs and course syllabi. Most courses were available at Research‐level institutions. More than half of the courses were offered within ...
... Developing quantitative ecosystem–scale expectations of habitat restoration projects and examining trade‐offs associated with alternative approaches has been a challenge for restoration ecology. Many of the largest freshwater lake restoration projects have occurred in Florida to remediate degradation to vegetated littoral habitats resulting from stabilized water levels, but effects across lake foo ...
... The coast of the Yellow Sea in China, like many other temperate coastal zones, has been experiencing a dramatic decline in the abundance of seagrass. Intensive efforts have been made to restore seagrass communities along the coast to restore the function of the coastal ecosystem. Transplanting adult Zostera marina shoots is labor‐intensive, time‐consuming, expensive, and detrimental to donor beds; ...
... The current study was undertaken to evaluate the success of a revegetation program on three sites within the Bauxite Residue Disposal Area at the Aughinish Alumina Ltd. refinery. This was achieved by determining botanical diversity, substrate conditions, and plant uptake. Two sites revegetated in 1999, with and without the use of gypsum, were assessed and compared to a site revegetated in 1997. Co ...

Abstract:
... Ecological restoration centers on the reestablishment of ecological processes and the integrity of degraded ecosystems, but its success also depends on public acceptance and support. In this study, we evaluated the short‐term ecological effects of different restoration treatments in Iceland. Furthermore, we tested the public perception of aesthetic and recreational values of these revegetated area ...

Abstract:
... Nature is most often valued in terms of its provision of ecosystem goods and services to meet human needs. However, such instrumental valuations, informed by ecological economics, are limited by the mainly anthropocentric orientation. We present a framework to assess anthropocentric and nonanthropocentric instrumental values of nature in a balanced way, in association with sustainability science. ...
... The Chesapeake Bay is one of the world's largest estuaries. Dramatic declines in the abundance and distribution of submerged aquatic vegetation (SAV) in the Chesapeake Bay over the last few decades led to a series of management decisions aimed at protecting and restoring SAV populations throughout the bay. In 2003, the Chesapeake Bay Program established a goal of planting 405 ha of SAV by 2008. Re ...
... This paper investigates the effect that manipulation of soil and vegetation conditions has on plant community development during attempts to create neutral hay meadow communities on a clay-capped landfill in Somerset, United Kingdom. The objectives are (1) to determine the effect of manipulation of soil and vegetation on the development of the target plant community, (2) to identify whether these ...
... An agent‐based modeling (ABM) framework was developed to support oyster reef restoration efforts in the Caloosahatchee River Estuary located within the encompassing Charlotte Harbor estuarine system, Southwest Florida. The modeling approach is novel for this shallow estuary which experiences heavily managed freshwater inflow known to be an ecological stressor to the estuary's oysters. The aims of ...
... Seagrass ecosystems have suffered significant declines globally and focus is shifting to restoration efforts. A key component to successful restoration is an understanding of the genetic factors potentially influencing restoration success. This includes understanding levels of connectivity between restoration locations and neighboring seagrass populations that promote natural recovery (source and ...

Abstract:
... Landscape context is an important factor in restoration ecology, but the use of landscape context for site prioritization has not been as fully developed. We used morphological image processing to identify candidate ecological restoration areas based on their proximity to existing natural vegetation. We identified 1,102,720 candidate ecological restoration areas across the continental United State ...

Abstract:
... Peatlands are the most efficient terrestrial carbon store on Earth, and deliver multiple other ecosystem services including climate regulation, water purification, preservation of ecological and archaeological records, etc. Disturbed and degraded peatlands do not provide the same ecological services and thus bear a significant cost to society. Because this cost may be alleviated by appropriate res ...
