reForest Alchemy: Returning biodiversity to inhospitable matrices of degraded habitats. Interview with Dr. Md. Mizanur Rahman by Willi Paul. Co-Presented by PlanetShifter.com Magazine & planetshifter.com
The policy makers and the conservation scientists must realize that conservation of biological diversity is not primarily a set-aside issue that can be dealt with by reserving or modifying management on huge landscape; rather, it is a pervasive issue that must be considered on every acre of land that they manage. For the matrix management we should consider the following points:
1) the importance of the matrix in key areas of ecology such as meta-population dynamics, habitat fragmentation, and landscape connectivity;
2) general principles for matrix management;
3) using natural disturbance regimes to guide human disturbance;
4) landscape-level and stand-level elements of matrix management;
5) the role of adaptive management and monitoring;
6) social dimensions and tensions in implementing matrix-based forest management; and
7) the relationship among patch occupancy, patch area and isolation.
We need effective models of our forest management, based on locally appropriate paradigms and application, in which the concept of sustainability is set in the broader context of managing production forests. Albeit a network of protected areas is necessary for conserving natural forests and their biodiversity. High forest fragmentations will be vulnerable for the biodiversity to sustain.
Woodlot Plantation forests, therefore, need to be managed for more than just timber production -- also for objectives such as supporting local livelihoods, biodiversity conservation, and environmental services, including carbon capture and storage.
For conserving biodiversity, this may require thinking in terms of managing the landscape as continuum of patches, corridors, and matrices.

Interview with Mizanur by Willi
Define sustainability for us?
Thank you Willi Paul! Sustainability is the meeting of present needs without compromising the ability of future generations to meet their own needs. In the conservation biology, sustainability describes how biological systems remain diverse and productive over time. FAO defines sustainable forest management as: The stewardship and use of forests and forest lands in a way, and at a rate, that maintains their biodiversity, productivity, regeneration capacity, vitality and their potential to fulfill, now and in the future, relevant ecological, economic and social functions, at local, national, and global levels, and that does not cause damage to other ecosystems. I define sustainable forest management as keeping balance between the demands of forest products and biodiversity conservation.
Is forest management now in the hands of scientists or the law makers?
Forestry is always both an arena of scientific investigation and a method for how forests should be managed. In forest management, managers define the nature of the problems at first, the second the scientist does the same but from the scientific point of view and finally the law makers take the bucket of facts from the scientists. So, forest management is a joint effort of forest managers, scientists and the law makers. Obviously, scientists are the play makers of this game.
Is subsistence the same as sustainability?
No, it is not the same; rather there is no significant difference between the subsistence and commercial forest. A subsistence forest addresses the subsistence needs of local people and keeps them gainfully employed. A subsistence forest can be a sustainable forest through reconciling the subsistence needs of people with conservation.
What is a "production forest?" What else "lives there?"
The forests which are used for the production of different commodities like timber, non timber products and other services are termed as production forests. The level of biodiversity depends on the forest type, location and management practices. Usually production forests offer less habitat diversity and support fewer species than do natural protected forests.
How do you propose to heal inhospitable sections of degraded habitat?
Protecting the degraded habitats from further destructions
Rebuilding connectivity among small adjacent protected areas by including intervening habitat and promoting reforestation of the landscape
Protecting forest edges against structural damage
Stopping colonization of exotics
Near natural management of the buffer zones
Managing forest matrix
Facilitating natural regeneration
Initiating rehabilitation and restoration programme
Making wildlife corridors through connecting areas of remnant forest to provide wider ranges and more protection for native plants and animals
Arresting the inevitable decline of the gene pool in isolated areas
Re-colonizing the wildlife species into their original habitat
Ex-situ conservation of gene pools of very rare species
"Structural diversity of both habitat remnants and surrounding matrix is an important factor for explaining plant population dynamics and ecosystem functions in human-impacted landscapes."
How does the forest become a matrix of scars and remnants? Who are the culprits?
A forest becomes a remnant in two ways:
1.ecosystem is partially removed, creating 'islands' surrounded by farmland; and
2. ecosystems is degraded by the loss of species and disruption of their ecological processes. The natural forest degradation occurs in different patterns, like in patches (e.g.), in waves (e.g. by urbanization) or as linear (e.g. by construction of roads).
The following factors are involved for the habitat destruction in the tropics:
faulty land ownership pattern
illegal and commercial logging
high demand of timber
scarcity of fuel wood
destruction of natural vegetation
inadequate valuation of forests as resources, inadequate protection
establishment of infrastructures and transport networks
construction of dams for hydropower sources
poverty, excessive extraction of non-timbering plants
lack of philosophical and ethical attitudes
encroachment and land grabbing
greed and corruption
wars and social conflicts
introduction of exotic species
Why the people are not responsible for the damage paying to fix it?
State is the owner of the forests in most of the third world countries. Sometimes the responsible authority does not try to sue the culprits due to several reasons: land disputes, ethnic conflicts, muscle power of the culprits, moving of illegal land-grabbers and loggers into the forest far ahead of the government, corruption of the forest authority, insufficient staffs and weakness of existing laws. Unlike most criminal organizations, the mafia has wide popular support in the Amazonian Rain Forests territory. So, it is very difficult to make the culprits responsible and fix the damage to pay.
There are many voices and opinions on "biodiversity." What is your definition?
Biodiversity is the variety; intra and interrelationships; and interactions of or among all floras, faunas and microorganisms living on this planet. It includes the variety of their genomes, richness, structures, habitats, natures and ecosystems.
Isn't biodiversity different to a logger vs. an eco-conservationist?
A logger defines biodiversity as the diversity of merchantable, quality, vital and valuable timbering plants in the forests. .:D
An eco-conservationist defines biodiversity as the diversity within species, between species and of ecosystems.
What are the leading resource management practices in this field?
I strongly believe that 'People Centered Conservation and Development' is the best management practice in the natural resource management. This is community based natural resource management, which reduces human pressures on biodiversity, leading to improved conservation; and aspires to combine social development with conservation goals. It deals with biodiversity conservation objectives through the use of socio-economic investment tools.
Are you advocating growing crops on all forest patches?
Not at all, growing crops on forest patches destroys the characteristics of the forests, makes the habitats inhospitable for natural regenerations and affects the biodiversity adversely.
Please define localization.
In the conservation biology, localization may be defined as the process of adopting conservation programme for a particular habitat in accordance with desired local "look-and-feel'.
How can the local population assist in fighting against clear-cutting?
Land based resistance
Awareness development against clear cut
Public relations campaigning for environmental sustainability
Helping law enforcing agencies to capture the illegal loggers and land grabbers
Forest Love Movement
Boycotting the illegal loggers within the social structure
