Researchers exploring the value of different types of timber across the Amazon rainforest have produced a fascinating choropleth map to illustrate their findings.
Retaining an intact riparian buffer during harvesting remains a challenge in some of the steeper, less accessible areas of planted forests in New Zealand, where roading constraints necessitate the extraction of timber across headwater catchments.
The gun ports developed in this period show a unique feature, that of a horizontal timber across the opening.
"There have been some complaints by several of the governors that their ability to use federal lands — whether it's for oil and gas, recreation, timber, across the board — that some of the heavy handedness on habitats don't allow for some of those uses, and they've come up with what they believe are innovative plans and workarounds," Zinke said.

Lay a piece of timber across the tops of two consecutive fence posts and use a spirit level to check that the tops are level.
Thirteen episodes follow four crews of timber cutters across a season in the forests of Northwest Oregon -- from mechanical failures and violent weather to snapped cables, runaway logs and dangerous equipment -- as they try to retrieve timber located on mountains too steep to reach with machines.
The nearest surface that a cart could have been driven along was probably around 300 to 500 metres away, as the settlement was only connected to dry land by a very narrow semi-derelict timber causeway across the marsh, almost certainly suitable only for pedestrian use, and that with some difficulty!
The scenarios are laid out according to the gradient with respect to the transitions from moderate to severe climate change impacts (B1, B2, A1, A2). Figure 3 Simulation results for relative changes in food production and timber harvest across three elevation bands (low, intermediate, high) for four global change scenarios in Visp.
The WB&A had a pair of timber bridges across its right of way.
