Eddy covariance methane measurements at a Ponderosa pine plantation in CaliforniaEddy covariance methane measurements at a Ponderosa pine plantation in California
Eddy covariance methane measurements Ponderosa pine plantation California
2009/11/19
Long term methane flux measurements have been mostly performed with plant or soil enclosure techniques on specific components of an ecosystem. New fast response methane analyzers make it possible to u...
Relationships between spruce plantation age, solute and soil chemistry in Hafren forest
dissolved organic nitrogen Acid neutralizing capacity soil chemistry
2009/6/8
Rain, throughfall, soil waters from surface peaty O horizon and deeper mineral B horizon, and stream water, were collected every four weeks for one year in a moorland catchment, and in four forested c...
The impact of the growth of new plantation forestry on evaporation and streamflow in the Llanbrynmair catchments
Annual water balances streamflow plantation forestry evaporation
2009/6/8
Annual water balances (1983-1995) for the Cwm and Delyn catchments at Llanbrynmair Moor in mid-Wales have been used to quantify the hydrological effects of the land use change in the Cwm from moorland...
Assessing soil calcium depletion following growth and harvesting of Sitka spruce plantation forestry in the acid sensitive Welsh uplands
soil calcium depletion Welsh uplands plantation forestry
2009/6/5
A simple mass balance has been used to estimate soil calcium depletion during the growth of a 50 year old Sitka spruce crop on acid, base-poor peaty podzol soils in upland Wales. Growth of the crop wi...
Cycling of nutrient base cations in a twelve year old Sitka spruce plantation in upland mid-Wales
Forestry base cations
2009/3/24
The effects of the early growth of plantation forestry on the biogeochemical cycling of potassium, calcium and magnesium have been investigated in a stand of 12 year old Sitka spruce and adjacent moor...
Effects of plantation forest clearfelling on stream temperatures in the Plynlimon experimental catchments, mid-Wales
stream temperature air temperature
2009/3/24
Hourly stream temperatures monitored over 28 months, which spanned a 3 month period of environmentally sensitive plot-scale harvesting of 20 ha. (20%) of the Nant Tanllwyth catchment (0.89 km2) on the...
The response of macroinvertebrates to artificially enhanced detritus levels in plantation streams
forestry detritivores old-growth conifers river management woody debris
2009/3/5
The leaves and wood from vegetation surrounding headwater streams constitute a major food source for aquatic invertebrates, providing they are retained upon the streambed and not transported downstrea...
The water quality of streams draining a plantation forest on gley soils: the Nant Tanllwyth, Plynlimon mid-Wales
water quality conifer harvesting nitrate phosphate alkalinity Plynlimon Tanllwyth groundwater
2009/3/5
The water quality of the Nant Tanllwyth stream in the Plynlimon region of mid-Wales is related to the key hydrobiogeological controls and the effects of conifer harvesting based on an analysis of rain...
The hydrochemistry of plantation spruce forest catchments with brown earth soils, Vyrnwy in mid-Wales
Gran alkalinity aluminium harvesting nutrients Vyrnwy water quality
2009/3/5
At Vyrnwy, in mid-Wales, a study of the hydrogeochemistry of two small spruce forested catchments, one a control and one felled midway through the study, shows a classic picture of rainfall inputs dam...
The bi-directional exchange of oxygenated VOCs between a loblolly pine (Pinus taeda) plantation and the atmosphere
bi-directional exchange oxygenated VOCs loblolly pine plantation atmosphere
2009/1/14
Using new in-situ field observations of the most abundant oxygenated VOCs (methanol, acetaldehyde, acetone, C3/C4 carbonyls, MVK+MAC and acetic acid) we were able to constrain emission and deposition ...
Seasonal variability of monoterpene emission factors for a ponderosa pine plantation in California
Seasonal variability monoterpene emission factors ponderosa pine plantation California
2009/1/6
Monoterpene fluxes have been measured over an 11 month period from June 2003 to April 2004. During all seasons ambient air temperature was the environmental factor most closely related to the measured...

Effects of free atmospheric CO2 enrichment (FACE),N fertilization and poplar genotype on the physical protection of carbon in the mineral soil of a polar plantation after five years
free atmospheric CO2 enrichment N fertilization poplar genotype physical protection
2010/1/13
Free air CO2 enrichment (FACE) experiments in aggrading forests and plantations have demonstrated significant increases in net primary production (NPP) and C storage in forest vegetation. The extra C ...
