|ECOLOGICAL RESEARCH IN NORTHERN ECOSYSTEMS|
|1.|| Regeneration Strategies of Competing Shrubs: Hardwood competition is
a major problem in forest renewal through silviculture. Understanding the
regeneration strategies of competing species would help in developing methods
to control the plants more effectively. Dr. Mallik's research concentrates
on the response of pin cherry, (Prunus pensylvanica), trembling aspen (Populus
tremuloides), beaked hazel (Corylus cornuta) and green alder (Alnus viridis
spp crispa) to conifer release treatments, by herbicides and manual brushsawing.
Vegetative regeneration by root suckering, stem base sprouting, rhizomatous
growth and seedling establishment are studied.
|2.|| Habitat Disturbance and Tree-Shrub Interaction Studies in the Northern
Ecosystem: Drastic ecosystem disturbance by wildfire or man-made manipulation
such as forest clear cuts often cause rapid growth of certain understory
species that interfere with conifer regeneration. The phenomenon of tree/non-tree
interactions plays a functional role in vegetation management and yet our
knowledge is very limited in this field. Ericaceous understory shrubs such
as Ledum groenlandicum, Kalmia angustifolia and Vaccinium spp. are excellent
plant materials for studying tree/non-tree interactions in conifer forests
of northern ecosystems.
|3.|| Natural Regeneration and Biodiversity of Old Growth Forests: Size-class
distribution of old growth white pine trees and seedlings are studies to
determine their ability to perpetuate by natural regeneration. Habitat diversity
and plant species diversity of the forests are also being studied to understand
the ecology of old growth forests and their role in providing habitats for
many different plant and animal species.
|4.||Other Expertise: (i) Instructional development on large-class teaching; (ii) Environmental impact assessment of large-scale development projects; (iii) Agro-ecological impacts of flood control projects in developing countries (iv) Consensus building in multistake holder groups on environmental management issues.|
