Activity of the Forest Keepers
in the Province of Trento
FORESTS IN TRENTINO
Total surface of Trentino: 620.000 hectars
56%
Surface covered by forests
346.000 hectars
276.000
215.000
hectares of productive forests (80% of the
forest)
hectares of planned productive
forests (78% of the productive forest)
growing stock 53.000.000 cubic meters
annual prescribed yield 447.000 cubic meters
135 logging firms
330-340 people employed
Annual processing of 380,000 net cubic meters
Annual Productivity between 1400 and 2000 cubic meters
Forest administration in the Province of Trento
10 Forest districts
37 Forest stations
171 Forest keeping zones
1 Director and 1 technical officer
1 Forest inspector and 2-4 agents
1 Forest Keeper
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.
Aim of the Forest Keeping service
According to the forest act n. 11/2007
management
improvement
the Public Forest property
enhancement
also with the goal of the conservation and balance of the ecological
systems.
The forest keepers can be employed in the
development of technical assistance for:
Public forest owners
Private forest owners
Enterprises involved in the management of the forest
property
Enterprises involved in the Forest harvesting
Support of rural development plan
Forest keepers
Vigilance functions
On the forest patrimony of public corporate administrations
On the respect of the laws in subject of environment and forests
Techinical functions
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:
Building wood for the own home
Fire wood
63%
households of Trentino that use firewood to integrate the
heating
86,000
tons
Annual quantities of firewood taken from public forests
3,5
tons
Average quantity of firewood that each asker will receive
annually
29%
About
24.500
Portions of civic use firewood distributed each year in the
province of Trento by the forest keepers
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
Kind of timber sales
cutted and
stacked
The owner takes care of
the cut processing and
logging and selling the
timber in stacks
Different price
depending on
assortment
standing
trees
presumed
assortments
The owner sells the plants
still standing to a firm
that takes care of the
cutting processing and
logging
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.
Single price.
No assortment
Different price
depending on
assortment
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
To trace the lines for the cable cranes
Estimation of the potential timber assortments
Monitor and control the work of cutting, processing and logging
Classify the logs in different assortments
Measure the timber
Follow the sale phases
Forest Keepers and the collaboration
with the SLOPE Project
The forest keepers took part in the setting phase of the project
to identify suitable areas for terrestrial and aerial surveys
They have provided guidance for
the job of marking and one of the
labels used was developed by
following their suggestions
Take part to the questionnaire
requirements users WP1
Forest keeper needs and requirements
and the slope project
Individuation of the annual cutting area
Estimation of the forest utilization cost
To trace the line for the cable cranes
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
Forest keeper needs and requirements
and the slope project
Estimation of the potential timber assortments
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
Exposure
Diameters
Slope
Branchiness index
Density
Evaluate the possibility of using the
spectral signatures of the canopy to
predict the presence of rotten wood.
Critical issues
Forest Road network and storage yards are not always optimal
Processor is not always usable in all contexts
Problem of processing waste (branches and treetops) created by
processors.
Accuracy of length measurements with processor
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
