Bosbeheer in beeld

Algemene Rekenkamer.

Ongewis of bosbeheer beoogde resultaten op termijn levert. Het beeld dat de laatste jaren is ontstaan dat Staatsbosbeheer overal in het land grootschalig bossen kapt, is onjuist. Onderzoek van de Algemene Rekenkamer wijst uit dat Staatsbosbeheer niet meer oogst dan er bijgroeit. Maar of de werkwijze van de grootste bosbeheerder van Nederland en andere boseigenaren op lange termijn de beoogde resultaten geeft, is echter op landelijk niveau onbekend.

Het rapport Bosbeheer in Beeld gaat over (Staats)bosbeheer en bossenstrategie. Het beeld dat de laatste jaren is ontstaan dat Staatsbosbeheer overal in het land grootschalig bossen kapt, is onjuist.

Onderzoek van de Algemene Rekenkamer wijst uit dat Staatsbosbeheer niet meer oogst dan er bijgroeit. Maar of de werkwijze van de grootste bosbeheerder van Nederland en andere boseigenaren op lange termijn de beoogde resultaten geeft, is echter op landelijk niveau onbekend.

“De landelijke bossenstrategie, door de rijksoverheid en provincies gezamenlijk in 2020 ondertekend, vereist landelijk 10 % meer bos op termijn. Die doelstelling wordt waarschijnlijk niet gehaald. Sinds 2013 verdwijnt er namelijk bij alle natuurbeheerders opgeteld meer bos in Nederland dan dat er aangeplant wordt. Er is ruim 6.000 hectare bos minder dan bij de start van de bossenstrategie.”

De conclusies laten zich samenvatten in de volgende punten:

    • Aantal gestelde doelen van de strategie worden niet gehaald.
    • Er is geen centraal inzicht in de resultaten van het bosbeheer.
    • Er is geen transparante afweging.
    • Er zijn geen financiële prikkels die aanzetten tot meer houtkap.
    • Art is geen garantie voor duurzaam bosbeheer.

De conclusies liegen er niet om. De gedane aanbevelingen zijn boterzacht en vooruitschuivend. Nadere informatie en afspraken moet gemaakt worden. Inderdaad. Had dat niet al gemoeten dan?

De bossenstrategie faalt. En dat is niet goed. Helemaal niet.

A survivor of vast forgotten woods

Margaret Wise Brown (author), Leonard Weisgard (illustrator) (1950) The Dark Wood of the Golden Birds. New York City: Harper & Brothers.

“As they listened, they began to understand the lives of the Forest, apart from themselves, indeed to feel themselves as the strangers where all other things were at home. […] Tom’s words laid bare the hearts of trees and their thoughts, which were dark and strange, and filled with a hatred of things that go free upon the earth, gnawing, biting, breaking, hacking, burning: destroyers and usurpers.

It was not called the Old Forest without reason, for it was indeed ancient, a survivor of vast forgotten woods; and in there lived yet, ageing no quicker than the hills, the fathers of the fathers of trees, remembering times when they were lords. The countless years had filled them with pride and rooted wisdom, and with malice.”

Forest Biometrics

I designed an intelligent pawn, called Equoi. It is in essence a simple concept, like that of the barometer or thermometer. It measures the mood of an object, place or process. The pawn is virtually full of sensors. Its application is easy: just put it on the table, ask your question, wait a moment and Equoi tells you the how and the what.

Here the global state of the forests is measured. What emerges is a result with a highly fragmented pattern. Indeed most of the forests are reduced, exploited, intersected. Deforestation has done its work and continues to do so. The left islands of forest, sometimes no more than ‘a group of trees’, are almost too small to survive as an ecosystem.

The colours of climate change

© Jack Kruf (2019) Climate change [fine art print, 1/1, sold]. Tilburg: private collection.

Following the Sustainable Development Goals, climate change is despite Covid-19 not forgotten. More so, the last is seen by scientists, managers and experts as an omen what we can expect when we keep disrupting the Earth ecosystem. Goal 13 is Climate Action: Take urgent action to combat climate change and its impacts. This goal has 5 targets:

    • Strengthen resilience and adaptive capacity to climate-related hazards and natural disasters in all countries.
    • Integrate climate change measures into national policies, strategies and planning.
    • Improve education, awareness-raising and human and institutional capacity on climate change mitigation, adaptation, impact reduction and early warning.
    • Implement the commitment undertaken by developed-country parties to the United Nations Framework Convention on Climate Change to a goal of mobilizing jointly $100 billion annually by 2020 from all sources to address the needs of developing countries in the context of meaningful mitigation actions and transparency on implementation and fully operationalize the Green Climate Fund through its capitalization as soon as possible.
    • Promote mechanisms for raising capacity for effective climate change-related planning and management in least developed countries and small island developing States, including focusing on women, youth and local and marginalized communities.

My personal expression of climate change is displayed above. I imagined the canvas of our world as a chess board with 8*8 fields and estimated the relatively most hurt ecosystems due to this change: coral reef (Pantone Living Coral ) and tropical rainforest (Pantone Forest Biome).

Government (Pantone Imperial Blue) is in fact a tiny spot on the canvas because it is doing not that much to tackle or change course. Most of the public leaders are still in denial or have no idea how to come into action. And we as citizens are not active either and go on with daily life. Storm (Pantone Storm Gray) is coming.

It is a personal art impression – or maybe better: an expression of an impression – to remind me that we will loose precious life if we continue this way. The present myriad of life is still so abundant in coral reefs and tropical rainforests, we can hardly imagine.

If you have seen these ecosystems, you understand and fall in love immediately. And if this happens there is not turning back, you want to protect and want to stay it forever to be there. I am in love, still (it is actually since 1977, the year I met (my) Professor Roelof Oldeman and with him did my first discoveries in and of the forest).

I am a realist, not a pessimist. I hear you thinking. But I did my homework as Wageningen University ecologist. Believe me, storm is coming, if we keep sitting on our hands. Maybe this small (art) expression is a small contribution to one of the targets of this sustainable development goal.

The colours of climate change will change over time. The coral reef and rainforest colours will disappear over time. A lot of gray will come in and the tiny spots of goverment remain insignificant as they are now,  I’m afraid. The driving political landscape is too dominant, too volatile and too focused on short term gains and profits. Remember I am not a pessimist, but a realist. The scientist in me remains. I like the colours. I hope they stay.

Rowan on forest floor

© Jack Kruf (2022) Rowan on forest floor. Breda: Private collection.

On the forest floor I found this small Rowan (Sorbus accuparia L.). I estimate 15 cm high. At the Ulvenhoutse Bos in Breda, the autumn light felt in on the forest floor in the late evening and reached this young tree. The colours are that of the true palette of autumn and where this time of year stands for: finalise a year of (here first) growth,  prepare for winter and get ready for the year to come. Letting the leafs go is crucial for a new start in spring. “How beautiful.
