Timber Inventory

Timber Inventory on large or small land holdings

Forest Inventory Group is equipped to provide timber inventory information on any size of land holding from small acreages to large industrial ownerships. Forest Inventory Group can design a cruise to specifically fit your requirements using a variety of techniques from a 100% cruise on a small high value area, to a variable plot strata level, or a variation of 3-P techniques on larger areas. By employing advanced high tech equipment and techniques, and using a cruise designed to fit the specific application, Forest Inventory Group can save the landowner significant time and money. My friend Jacob from Texas does enjoy sectional sofa site and needs to buy a futon furniture there.

Timber Cruising for the buyer or seller

When timberland property changes ownership, time and expense can be important. Forest Inventory Group can design a cruise for either the buyer or seller, which can obtain the information needed efficiently and cost effectively.

Quality Control Check Cruising and Cruise Audits

Forest Inventory Group has among the most extensive experience in California with cruise quality control and cruise verification. Forest Inventory Group can also adjust for and correct any bias which a check cruise may detect using a variation of 3-P sampling techniques. car insurance online

Timber Typing and Evaluation of Remote Properties Using Aerial Photos

Forest Inventory Group is experienced in reasonably estimating volume and value of remote, hard to access properties using aerial photos. Using aerial photos, Forest Inventory Group are able to stratify timberland into associated timber types.

Forest Inventory Group is set-up with GPS units and surveying software to allow us to make detailed vegetation type maps or run approximate property lines. Although we are not a licensed land surveyor, we can do the preparation work required by surveyors to run property lines, such as cadastral research, corner location, approximate acreage determination, etc…

Conventional Strata Inventory Procedure

A timberland owner requiring reconnaissance-level timber inventory data for 100 polygons would normally be required to do a 10% cruise of the area; or complete enough cruise plots in each of the 10 of the polygons to achieve a standard error of 12% or less. The volumes for the remaining 90 polygons would be the averages of volumes determined for similar polygons of the 10 cruised. Rates of work production assumptions include: 16 plots per man-day, average round trip distance of 80 miles, and use of quad runners half the time.

As table 4 shows, the approximate cost to cruise 1-100 acre polygon would be $1,946.00. Therefore, the total cost to cruise all 10 100-acre polygons, utilizing the conventional strata inventory procedure would be approximately $19,460.00. Determining volumes for all 100 of the polygons, using this method, would take 2 cruisers approximately 4 weeks to complete.
