Chantal Helm BSc MRes PhD
is a terrestrial ecologist with wide ranging interests in wildlife
management, conservation, plant ecology, plant
herbivore interactions and monitoring and survey techniques of
wildlife. She has extensive research experience in
large conservation areas in South Africa including the Kruger National
Park and hence has an understanding of
conservation working practices in Southern Africa. Projects she has
undertaken as part of her studies include
producing an ecological assessment and management plan for an 1100 ha
game reserve and an investigation of
habitat selection, behavioural ecology and population dynamics of two
closely related wildebeest species. Both
projects involved extensive fieldwork. Her doctoral studies were
carried out in collaboration with academics from the
Animal Ecology Research Group at the University of the Witwatersrand,
the Centre for Tropical Studies and the
University of Cape Town. The thesis investigates population dynamics
and autecology of a keystone savannah tree
specifically focussing on responses to disturbances such as herbivory
and fire and includes a modelling component.
The doctoral examiners indicated that the study would set a bench mark
for future studies on African savannah trees
and Chantal has since had four papers published in peer reviewed
international journals, with a further four papers
expected. She has presented the results of her research at
international conferences held in various locations
including South Africa, Australia and France.
academic studies have enabled Chantal to develop an extensive set of
ecological skills including wildlife habitat
assessments, plant identification, vegetation surveying, water quality
monitoring and alien plant control. Chantal also
has experience in statistical data analysis, population modelling and
basic GIS, with proficiencies in ArcGIS, Photoshop
and a variety of graphic viewing and manipulating programmes. Having
been employed as a teaching assistant and
lecturer during her doctoral studies at the University of the
Witwatersrand, she spent a year as a Teaching Fellow at
the University of Bath after completing her doctorate, teaching plant
diversity, ecology and biostatistics to
currently teaches the ecology components of the BSc and MSc
Environmental Management degrees at the
University of Hertfordshire and has responsibility for leading several
modules. She is making extensive use of the
University's Bayfordbury Field Station near Hertford as part of her
teaching and research, in particular for surveying
small mammals, amphibians and bats. She is currently studying for the
postgraduate certificate in Teaching and
Learning in Higher Education.
