1. Undertaking large‐scale forest restoration to generate ecosystem services

Author:
Lamb, David
Source:
Restoration ecology 2018 v.26 no.4 pp. 657-666
ISSN:
1061-2971
Subject:
ecological function; ecosystem services; ecosystems; forest restoration; forests; issues and policy; landscapes; natural regeneration; plantations; planting; reforestation; risk; species diversity
Abstract:
... The global community is seeking to substantially restore the world's forest cover to improve the supply of ecosystem services. However, it is not clear what type of reforestation must be used and there is a risk that the techniques used in industrial timber plantations will become the default methodology. This is unlikely to be sufficient because of the well‐known relationship between biodiversity ...

Subject:
data collection; ecology; funding; memory; monitoring; people; risk; surveys; wastes
Abstract:
... Many important ecological management issues can only be addressed by long‐term monitoring or through studies carried out over extended periods. But such studies require institutional settings that ensure funding is sustained and that data arising from these studies are securely managed. Recent experience suggests both are difficult to achieve. This is because management agencies and research bodie ...

Abstract:
... Understanding the components of water consumption of a crop or pasture through evapotranspiration is important for improving water management. In this study the FAO dual crop coefficient methodology has been used in conjunction with a portable evapotranspiration chamber in-situ, to quantify the basal crop (Kcb) and soil evaporation (Ke) coefficients of a pasture as a function of leaf area index an ...

Abstract:
... The estimation of actual crop evapotranspiration (ETc) from any given land cover or crop type is important for irrigation water management and agricultural water consumption analysis. The main parameter used for such estimations is the crop coefficient (Kc). Spectral reflectance indices, such as the normalized difference vegetation index (NDVI) and the crop coefficient of a specific crop or pastur ...

Abstract:
... There is growing interest in using multi-species plantation systems when undertaking reforestation for timber production. Such plantations can have ecological and socio-economic advantages over those of traditional monocultures. Despite increasing evidence about the functional advantages of increasing species richness in reforestation, there are few silvicultural guidelines to assist in the design ...

Abstract:
... In 1986 the paths of two men crossed – one who had started a Trust fund to purchase land for conservation and the other who was looking for land to test his hunches about forest regeneration. The two joined forces and the subsequent 30 years saw a growth in both the Trust and the forest such that today it is a 1,500 ha regrowth rainforest with a network of indefatigable supporters. ...

... Biosynthesis of steroid hormones in vertebrates involves three cytochrome P450 hydroxylases, CYP11A1, CYP17A1 and CYP19A1, which catalyze sequential steps in steroidogenesis. These enzymes are conserved in the vertebrates, but their origin and existence in other chordate subphyla (Tunicata and Cephalochordata) have not been clearly established. In this study, selected protein sequences of CYP11A1, ...

Abstract:
... The successful establishment and growth of mixed-species forest plantations requires that complementary or facilitatory species be identified. This can be difficult in many tropical areas because the growth characteristics of endemic species are often unknown, particularly when grown at potentially higher densities in plantations than in natural forests. Here, we investigate whether wood density i ...
