Height-Diameter Allometry for Tree Species in Tanzania Mainland

Total tree height (H) and diameter at beast height (D) are important independent variables in predicting volume, biomass, and other forest stand attributes. However, unlike D measurement, which is easy to measure with high accuracy, H measurement is laborious. This study, therefore, developed H-D relationships for ten different forest types in Tanzania Mainland. Extents in which climate and forest...

ECOWAS, FAO, Sida Project Focuses on Sustainable Forest and Land Management

West Africa’s forests and wetlands are an important source of livelihoods, food and fuel for millions of people but are threatened by deforestation and forest degradation. The five-year project will improve knowledge of forest dynamics and support implementation of priorities outlined in the ‘Convergence Plan for the Sustainable Management and Use of Forest Ecosystems in West Africa,’ includ...

George Monbiot Q + A - How rejuvenating nature could help fight climate change

Natural climate solutions let nature do the hard work in the fight against climate change by restoring habitats such as forests and wetlands. This could absorb carbon dioxide from the atmosphere and help biodiversity thrive. Stephen Woroniecki - a PhD Researcher in Climate Change Adaptation from Lund University in Sweden - discusses how this approach could address the ecological crisis with Guardi...

Denmark among the treetops

Denmark has been waiting for two years for its forest tower but it has been worth the wait as the Camp Adventure Park now has a 900-meter treetop walk connected to a 45-metre tall observation tower that creates the opportunity to take a walk above the treetops and experience the stunning nature of the preserved forest from another perspective. Source: Timberbiz The tower and treetop walk is as a s...

Country diary: four button-black eyes stare in our direction

Marston Vale, Bedfordshire: Beyond the reedbeds of the wetlands reserve, Chinese water deer sniff us out at 30 pacesSuspended six metres up from the ground, the Tower hide reinforces my faith in the oft-stated view that there are more wetlands in Britain today than at any time in the past hundred years. The wood-slatted, window-bright crow’s nest gives unparalleled views over a “forested” wi...

Potential effects of climate change on riparian areas, wetlands, and groundwater-dependent ecosystems in the Blue Mountains, Oregon, USA

Riparian areas, wetlands, and groundwater-dependent ecosystems, which are found at all elevations throughout the Blue Mountains, comprise a small portion of the landscape but have high conservation value because they provide habitat for diverse flora and fauna. The effects of climate change on these special habitats may be especially profound, due to altered snowpack and hydrologic regimes predict...

Factors contributing to shore pine (Pinus contorta subsp

<p>Recent Forest Inventory Analysis (FIA) plot remeasurements revealed a statistically signi­cant 4.6 percent loss of shore pine (Pinus contorta subsp. contorta) biomass in Alaska despite negligible harvest, with greater losses among larger size-class trees (Barrett and Christensen 2011). Shore pine is one of four distinct subspecies of Pinus contorta (Critch­eld 1957); it occurs on coasts...

Publication date: 1 June 2019Source: Forest Ecology and Management, Volume 441Author(s): Brandon L. Edwards, Scott T. Allen, DeWitt H. Braud, Richard F. KeimAbstractForested wetlands play a vital role in the coastal zone, but their vulnerability to coastal change—and the impact to high-value ecosystem services—is not as well established as that of more seaward systems such as saltmarsh and man...

Call for wetland decade under the U.N. decade on ecosystem restoration (2021-2030)

The environmental health of wetlands across the world is deteriorating. The authoritative Global Wetland Outlook released by the Ramsar Convention on Wetlands in 2018 highlighted an alarming trend in wetland loss; at least 35 percent of the world's natural wetlands have been lost since 1970....
