Metsäkartoituksia

Metsäkartoituksia, or forest inventories, are systematic procedures for collecting data about forest resources. These inventories are crucial for understanding forest health, growth, and potential for timber harvesting, conservation, and other land management activities. The process typically involves field measurements and data analysis.

Fieldwork for a metsäkartoitus may include measuring tree species, diameter at breast height (DBH), tree height, and crown closure. The location of sample plots or individual trees is often recorded using GPS technology. Soil characteristics, undergrowth vegetation, and signs of disease or insect infestation are also frequently documented. Remote sensing techniques, such as aerial photography and satellite imagery, are increasingly used in conjunction with ground-based measurements to provide a broader overview and to identify changes over time.

The data collected from metsäkartoituksia is used to estimate timber volume, assess forest productivity, and model future forest development. This information is vital for sustainable forest management practices, allowing forest owners and managers to make informed decisions regarding silvicultural treatments, harvesting plans, and conservation efforts. Metsäkartoituksia also play a role in national and international forest reporting, contributing to a global understanding of forest cover and its changes. The frequency of these inventories can vary depending on the objectives and the dynamics of the forest being studied.
