The management of our forests is to develop through the general objective structure richer mixed stands, become more complex. In addition, the growth course of our stocks frequently differs from the old planning principles, the yield tables as example are stored in the app "use planning in pure stand," from.
With the use planners of practitioners in the field on his smartphone or tablet can assess the use of masses he should take in pure and mixed stands if he wants to manage the stock according to the new recommendations of the NW-FVA for basal area at staggered crown thinning. Moreover, the inventory data and usage approaches for later processing in the office can be saved.
An example will illustrate the application: In a 70-year-old beech-spruce mixed stands a floor area of 24 m² / ha and a top height of 25 m was measured for the book. For spruce, the corresponding values were 10 m² / ha and 29m. First, the app user selects the button again so that all old data will be deleted. Thereafter he presses the "line +" and enters the mask to enter the tree species. He then enters the appropriate values. He has it set out the possibility of the respective layer and blend shape. After each entry is a line for the input tree appears on the main screen. For the missing spruce App user repeats the process. With each new inventory line of the mixing ratio, the stocking and the proposed usage amount to be recalculated. In the example, the stock has a stocking level of 1.1, and it should be 47 m³ / ha beech and 29 m³ / ha spruce be removed. The values are based on the assumption that the mixing ratio is kept constant. The user can change again and delete it by clicking on the tree species lines entered. Are all stock lines detected, the proposed use amount can either be accepted or changed interactively own estimation. Then the values can "save as" with the button are stored in the SQLite database the app in the directory "/ fTools" on the SD card with the name "nutzungsplaner.db" is. The database file may eventually via email, transmit a cloud (Dropbox, OwnCloud) or a data cable to your own PC for further processing with other programs. For the understanding and treatment of the SQLite file especially the free Firefox add-on SQLite Manager recommends. With the option button, the options menu can be activated at any time, be it for the help call or to end the active app.
