• Een belangrijke uitdaging
• Het verschil dat Analog Forestry heet
• Forest Garden Products Certificering
• Stappenplan, kosten en opbrengsten
• Twee voedselbossen in aanleg in Nederland
13. In de natuur neemt de biomassa over de
tijd vanzelf toe
14. Veel herstelplannen slaan de plank mis
Veel
herbebossings-
programmas
zien niet in dat
de optimalie
biodiversiteit
van een
(tropisch) bos
voor slechts
1%
uit bomen
bestaat.

25. What is Analog Forestry?
Analog forestry is an ecological restoration tool that helps to
restore the life support systems of the planet – represented by
healthy, biodiverse ecosystems
Restoring the planet’s life-support systems.
27. Restoring the planet’s life-support systems.
Planting forests that are similar in architectural
structures and ecological functions to the original
climax forest.
Analog Forestry
28. History
Restoring the planet’s life-support systems.
• Initially practiced in Guatemala and California in the 1970s
• Based on the traditional ‘home gardens’ of tropical Asia
• Concepts were tested on the ground in Sri Lanka in 1983
• The International Analog Forestry Network was created in 1996
to develop and popularize the AF model
30. Restoring the planet’s life-support systems.
1. Record the structure
of the natural forest
with the help of a
physiognomic
formula
2. Mapping and
ecological evaluation
of the degraded area
that shall be
reforested

31. Variables for constructing Physiognomic Formula of Vegetation.

32. Principle 1 Observe and record
Examples of Formula
Example 1
B7cdm, B6izn, B6idm, B6rdg; H2c, H2-6r, L2-7c; S2-6c; E2-7i; P6i
Example 2
B8rdm, B7idm, B6idg, B5rdg; H2c; S2-6i; L2-6c; T8c, E7-8h; S3h
33. Once an understanding of the components of the ecosystem
in question is gained, it is possible to evaluate the species
within it in terms of the management goals.
