Endangered Wildlife Trust (EWT) Launch National Public Roadkill Survey
Recently GVI attended an EWT conference at the Johannesburg
Country Club hosted by Wendy Collinson from their Wildlife & Transport
Progamme. We were invited to attend because Wendy actually came to South Africa
as a volunteer at one of our previous wildlife research projects at Vanetia,
Limpopo.
She is addressing the fact that in Africa there is very
little data, or even methods for analyzing roadkill impacts at the moment.
Despite the fact that we have the 18th largest road network in the
world, there is virtually no money spent on mitigations measures to protect our
wildlife due to lack of data. Mainly nocturnal animals are being affected, such
as Civets and Nightjars especially, probably being blinded by people’s car
headlights. However, animals of conservation concern are also often affected;
Wild Dogs seem particularly susceptible - 4 deaths occurring in Kruger last
month, 7 in the Waterberg last year, as well a very recent on Balule North.
Wendy is trying to identify roadkill hotspot areas across
South Africa in the first stage of the study, so that potential mitigation can
be planned – examples which have been used in other countries include rope
bridges, underpasses, overpasses etc. They will then investigate the
characteristic features of these hotspots to see if there is anything that can
be managed to reduce roadkill impacts such as burning, planting vegetation,
modifying fencing etc or which might relate to the type of mitigation measure would be appropriate to install.
The main envisaged power of this initiative will be public
participation to collect enough data about the entire country’s road network. A
smart-phone App will available soon through the EWT’s website to promote data
collection by allowing people to send in photos of roadkill from location. This
will eliminate observer error as identifying roadkill is not always the easiest
of jobs!
Wendy has also had a lot of help with data collection from
GVI volunteers for her pilot studies leading up to having her project being
incorporated into the EWT’s Wildlife & Transport Programme. Some initial
findings from the pilot study around the Mapungubwe National Park area are that
reduced road proximity to fencing, higher grass heights/densities and open
areas are significant (ie more roadkill incidences). Interestingly, traffic
density was not a significant factor of elevated roadkills – this data only
represents one comparatively small area of South Africa, but it could suggest
that vehicle disturbance levels force animals to seek less busy alternatives.
