Welcome to Forest Productivity.com! We aim to provide visitors
and forestland managers with the most current, unbiased,
science-based, forest productivity information available
in support of best management decisions on forestlands.
A key objective of the website is that natural resource
managers will be enabled and equipped to make better, cost-effective
forest management decisions to optimize forest productivity.
This website is not intended to take the place of a professional
forester. For specific recommendations on a particular tract,
contact a state agency service forester, consulting forester,
Extension forester or forest industry landowner assistance
Features of the forest site include those relating to
the soil, topography, hydrology and overall productivity
potential of the property in question. Understanding
these features and how they affect the growth and survival
of your forest is a critical first step.
Site preparation is carried out to create a favorable
environment for the successful establishment and growth
of seeds and seedlings. Practices may include chemical,
mechanical and/or natural (burning) vegetation control,
and site enhancements such as bedding, disking, windrowing,
and a whole host of related activities
Forest genetics is the study of hereditary variation
in trees. Tree improvement is the application of forest
genetics to field practice. Tree improvement work is
accomplished by testing tree family selections and determining
which will grow best when planted on certain sites or
in specific geographic locations. Tree improvement focuses
on a few key traits: volume yield, resistance to diseases
(i.e. fusiform rust), branch angle, and form.
Forests may reproduce more successfully when special
efforts are made to encourage regeneration. Either
artificial regeneration that involves planting seeds
or seedlings, or natural regeneration that relies
on existing seedlings or seed may be used. For specific
recommendations on a particular tract, contact a forest
service forester, consulting forester, or industrial
landowner assistance forester.
Fertilizers are applied to over a million acres of
forestland annually. Some trees, particularly slash
and loblolly pines, can respond dramatically to proper
fertilization. Response is best when other intensive
management practices are being applied and on nutrient
deficient sites. Knowledge of your soil type and soil
conditions, combined with a soil test to determine
the site’s soil fertility status, will help identify
sites and stands that will respond to specific fertilizers.
Forest herbicide application provides gains in seedling
survival and growth rates by allocating water, nutrients
and sunlight to the crop trees. Herbicide use also
reduces fire hazard and improves access to timber
stands. It can also be used to manipulate and improve
wildlife habitat and to control invasive plants.
