The term “Precision Forestry” is being used more frequently in the forest products industry. This paper defines two broad categories of precision forestry as 1) using geospatial information in forest management and planning, and 2) site-specific silvicultural operations. One case study is presented for site-specific application of herbicides and fertilizers in herbaceous weed control activities...
To understand the biomass condition in the forestry areas, the detection for individual trees becomes an important topic. For forestry management, the canopy may be described with several parameters, e.g., number of stems, stand position, tree height, timber volume, canopy cover, etc. Traditional methods rely on field measurements, imagery, and radar data to derive the canopy information. Follo...
Following a search of the World Wide Web and a publication review, a large number of forestry software applications were identified. Although the search was worldwide, language barriers directed the search towards English speaking nations with developed forestry industries such as the United States, Canada, Australia, New Zealand and Britain. Over sixty forestry applications were identified and...
Abstract: Explaining land use change in Mexico requires understanding the behavior of the local institutions involved. We develop two theories to explain deforestation in communities with and without forestry projects, where the former involves a process of side payments to non-members of the community and the latter of partial cooperation among community members. Data collected in 2002 combine...
Clean Development Mechanism (CDM) forestry project development requires highly multi-disciplinary and multiple-source information that can be complex, cumbersome and costly to acquire. Yet developing countries in which CDM projects are created and implemented are often data poor environments and unable to meet such complex information requirements. Using Cameroon as an example, the present pape...

Over-harvesting of forestry resource, primarily trees, through illegal logging has been exceptionally regular for decades. In the context of this worldwide issue, a mathematical model considering the joined impact of legal and illegal logging of trees from forestry biomass using delay-driven ordinary differential equations is proposed. For the set of equations, we have taken immature, mature fo...
