Near Nature Forestry and Harvesting Operations Hanns H. Höfle University of Göttingen Lower Saxony State Forest District of Bovenden

Slide 2

Close to nature ranger service and gathering operations Why near nature ranger service? What is near nature ranger service? What are the conditions for collecting operations in stands of near nature ranger service? How to manage this circumstance as for innovation, efficiency, security and the earth? Conclusions

Slide 3

Close to Nature Forestry: Reasons New thoughts inside the ranger service group Outside powers put weight on ranger service

Slide 4

Close to Nature Forestry: Example Lower Saxony (1) Site insurance and site-adjusted species sythesis Mixed stands Ecological similarity Natural recovery Improvement of stand structures Harvesting of target breadth trees Conservation of old and dead trees; security of uncommon and imperiled types of greenery

Slide 5

Close to Nature Forestry: Example Lower Saxony (2) Establishment of a system of ensured woodlands 9. Arrangement of unique non-wood administrations 10. Advancement and tending of woodland edges 11. Timberland assurance taking after biological points (IPM) 12. Environmentally situated natural life administration 13. Naturally well disposed woodland innovation

Slide 6

Close to Nature Forestry: Example Lower Saxony (3) Long-run biological project for state backwoods in Lower Saxony ("LÖWE-Programm") Developed by Prof. OTTO Agreed upon between Ministry of Agriculture and Ministry of Environment First case in Germany Taken up by different states ("Länder") in Germany (and different nations, e.g. DK) Mandatory for state woodlands Recommendation for other backwoods proprietors

Slide 7

Close to Nature Forestry: Main Features Forests are comprehended as environments (blended stands, site adjusted species, rich and mosaic sort stand structures) Incorporates the standards of various use ranger service Aspects of nature protection and organic differing qualities are checked Disturbances ought to be minimized (consistent spread, insignificant mediations, negligible harms to stands and soils) Risks ought to be maintained a strategic distance from

Slide 8

Close to Nature Forestry: Characteristics of Stands Variation of age and size of trees Inhomogeneous stand structure (vertically and on a level plane) Reduced perceivability Obstacles through understory, recovery, dead timber on the ground Regeneration in crevice like structures – > littler zones of operations, more prominent consideration in felling operations Target breadth reaping –> extensive size trees Large trees –> all the more dead branches in the crowns Old and dead trees aggregate in the stands

Slide 9

Characteristics of Stands: Consequences Harvesting = most risky operation in ranger service; felling, thusly, most perilous inside gathering; falling branches, bumbling and tumbling down, cutting trees under strain in the wrong way Risks are much more prominent now because of: Greater tree measurements Impaired perceivability More snags in the stands and on the ground Higher measure of dead timber Everybody is permitted to enter the timberland

Slide 10

How to manage these dangers? Security is the duty of the enterpreneur Safety precedes benefits Awareness raising Good case Systems approach

Slide 11

Before an operation begins (1) Risk examination is required (once for the standard, dependably for the extraordinary circumstance) Refresher preparing for timberland laborers (e.g. directional felling, managing exceptional cases, for example, inclining trees, consciousness of wellbeing) Prescribed arrangement of sliding lines is compulsory (chosen, exchanged to the territory, set apart in the stand) Trees to the felled are stamped + ideal felling bearing + indication to dangers Hindering trees are likewise checked and should be felled in any case

Slide 12

Before an operations begins (2) Choice of the ideal working procedure Parameters: kind of trees – sum and sort of dead timber (none – in the crown – dead trees) Standard operation Variation for forward, sideward … inclining trees Use of water powered lifter Felling with winch bolster Fully automated gathering frameworks Written target understanding (work request)

Slide 13

During an operation Hindering trees are felled as the principal ones Dead trees may likewise be felled (Dead trees – 5/ha - equally dispersed previously; now, they are packed in part of a stand so as to reduction dangers) Optimal reaping technique is utilized (+ legitimate planning, high buoyancy tires, biodegradable oils and ointments) + directional felling Safety tenets are complied (continous contact between specialists, escape courses … ) Control of operation and results

Slide 14

After an operation Damages to the dirt? Harms to the rest of the trees? Harms in the recovery? Wellbeing viewpoints: right felling method, escape courses?

Slide 15

Productivity and Economics in Close to Nature Forestry (1) Natural recovery as opposed to planting „Biological robotization" substitutes tending (at any rate in part) Situation to begin from (e.g. unadulterated beech versus immaculate spruce stands) Tree measurement and timber quality

Slide 16

Productivity and Economics in Close to Nature Forestry (2) Larger trees to be reaped versus More cautious and more entangled operations Smaller add up to be cut per range? (clear-cuts versus thinnings) Benchmark? (completely automated gathering operations, landscape, wage rates, streamlined supply chains … ) Non-wood administrations?

Slide 17

Safety Successful security crusades (see case in Switzerland, France, Germany … ) Safety pays Forestry is for individuals!!

Slide 18

Conclusions Close to nature ranger service is a decent case of feasible backwoods administration It is various use ranger service The financial matters are promising – yet … Environmentally well disposed collecting operations (Reduced Impact Logging, Codes of Good Forest Practice) Safety by method for a frameworks approach Stand conditions change: versatile administration is required in the feeling of DEMING\'s „plan – do – control – act!
