Set of methods for the MLA approach
Field based methods
The field survey was a combination of relatively standard
scientific descriptions of terrain, soil and vegetation, and of equivalent
observations from a local people's perspective. Typically the team would be 7-10
people: 2-4 local informants, the soil specialist, the botanist, the
ethnobotanist, a recorder and 1 or 2 assistants.
complete physical description of the terrain, as well as local
people's description of its use history, the location's importance
for different use categories, accessibility, local names for the
location, the land unit and the vegetation, etc.
Herbs transect: a
40x5 meter transect line was subdivided into 10 subunits. In each of
these, herbs, climbers and other smaller plants were recorded. A
botanist would name the species or collect the specimen while the
ethnobotanist would ask informants for local names and uses.
Tree sample unit:
a new and versatile sample unit was developed, suitable for rapid
assessments of tropical forest in heterogeneous areas. Species,
height and girth of a maximum of 40 trees was assessed for each
forested site, which allow
calculations of density and basal area. Apart from that, local
informants gave information about the use(s) of each tree.
two holes were drilled with a Belgi augur and one profile of 60cm
depth was dug to make a complete physical description of the soil. A
local informant, selected by the community itself for his knowledge
of soil and cultivation, was asked for local assessment and
descriptions of the soil's qualities, its name and its potential
use. Download datasheet
