The forest keeper ensures the service in the circumscription to which it belongs and is directly responsible for the service in the keeping zone entrusted to him.Maintains the necessary connection relationships and cooperation with the representatives of the public forest owners and the forest authority.

1 Director and 1 technical officer

Aim of the Forest Keeping serviceAccording to the forest act n.

11/2007

The forest keepers can be employed in the development of technical assistance for:

Public forest owners

Enterprises involved in the management of the forest property

Enterprises involved in the Forest harvesting

Support of rural development plan

Private forest owners

Forest keepers

Techinical functions

Vigilance functions

On the forest patrimony of public corporate administrationsOn the respect of the laws in subject of environment and forests

Management of the “civic uses” in forest (firewood)To follow the operations connected with the forest utilizations in the public forests and to guard that the same are used in conformity of the technical and contractual prescriptions.

Usi civici

Civic uses

the Civic Use is the right of every inhabitant of a municipality or community, to enjoy the fruits of a collective ownership good (typically woods and pastures) to satisfy the basic needs of life.

When the good of the collective ownership is the forest, the civic use right are:

Fire wood

Building wood for the own home

households of Trentino that use firewood to integrate the heating

Annual quantities of firewood taken from public forests

Average quantity of firewood that each asker will receive annually

63%

29%

3,5 tons

86,000 tons

Portions of civic use firewood distributed each year in the province of Trento by the forest keepers

About24.50

0

Average annual number of portions of firewood distributed by any forest keeper

Silvicultural importance of civic uses

The civic use allow to perform actions such as thinning that are without economic convenience for the public owners.

With passing of the time, however, the more comfortable and accessible areas are less and less. On the other areas the utilizations are carried out by specialized firms, then the material obtained is distributed as firewood to askers, that pay only the cost of intervention.

Commercial forest utilization

cutted and

stacked

standing trees

presumed assortments

The owner takes care of the cut processing and logging and selling the timber in stacksDifferent

price depending on assortment

The owner sells the plants still standing to a firm that takes care of the cutting processing and logging

Single price. No assortment

The owner sells the timber before cutting estimating the quantities of each assortment and agreeing with the buyer on the required assortments and the delivery period.

Different price depending on assortment

Kind of timber sales

Percentage of forest keeping zones where prevails the sale of timber cutted and stacked

Role of the forest keepers in the commercial forest utilizations

Individuation of the annual cutting area

Estimation of the forest utilization cost

Estimation of the potential timber assortments

To trace the lines for the cable cranes

Monitor and control the work of cutting, processing and logging

Classify the logs in different assortments

Measure the timber

Follow the sale phases

The forest keepers took part in the setting phase of the project to identify suitable areas for terrestrial and aerial surveysThey have provided guidance for the job of marking and one of the labels used was developed by following their suggestionsTake part to the questionnaire requirements users WP1

Forest Keepers and the collaboration with the SLOPE Project

Individuation of the annual cutting area

Estimation of the forest utilization cost

To trace the line for the cable cranes

Forest keeper needs and requirements and the slope project

Implementation of models based on DTM, DSM, CHM data and and GIS information about forest road network to obtain a segmentation of the forest in different areas with different costs of utilization

Estimation of the potential timber assortments

Forest keeper needs and requirements and the slope project

Implementation, through sample areas, of a predictive model for the estimation of the possible assortments obtainable from a particular forest area based on parameters easily detectable such as:Medium height

Diameters

Branchiness index

Density

Slope

Exposure

Evaluate the possibility of using the spectral signatures of the canopy to predict the presence of rotten wood.

Critical issuesForest Road network and storage yards are not always optimal

Problem of processing waste (branches and treetops) created by processors.

Accuracy of length measurements with processor

Processor is not always usable in all contexts

Specific technical knowledge and specifications (GPS, GIS) are not known to all the forest keepers

Optimal situation, wide space, roads suitable for trucks

situation more difficult, less space, not very wide road

Piles of branchwood created by processors could be a problem when the area can not be reached by a wood chipper and truks

TRAINING

Specific technical knowledges and specifications (GPS, GIS) are not known to all the forest keepers

The SLOPE project can be an opportunity to improve these knowledges
