Wildlife Assessment - Kalahari Ecosystem (WAKE)
Reconnaissance trip funded by University of Alberta FDIC
Dr. Lee Foote University of Alberta, Edmonton, AB Canada
Ph (1) (780) 492-4020
Basic Motivation:
Responsible conservation requires we continually work to develop better ways let ecosystems meet the needs of people while ensuring the long-term maintenance of both human cultures and ecosystem integrity.
Such conservation is necessarily an adaptive process that goes on forever because of incessant changes in global economics, climate, population, and knowledge.
Direct enumeration
Indirect enumeration
Based on the success of snow track survey protocols in Alberta, we propose to use local expertise to help develop a similar technique for sand-bed spoor analyses, enumeration, biodiversity analysis and visibility correction factors for aerial surveys.

Kalahari Lion track
Rationale for specific biodiversity measures proposed:
Why Track Surveys?
1. Dependable; if track is there, animal was there
2. Time-integrated; captures daily cycle of movement
3. Low-impact; non-invasive, no wildlife handling needed
4. Participatory; features and incorporates local knowledge
5. Statistically robust; sample size, independent variable & land use treatments prescribed.
6. Low-tech, low risk; less prone to equipment or personnel failure
7. Less confounded by available water sources (some sp).
8. Comprehensive presence/absence detection; good way to detect very rare species.
9. Compatible with aerial and ground surveys; provides a visibility correction factor (VCF).

*= species indigenous to KTFP as benchmark (2001 & later)
2. Wildlife species may be predicted from vegetation and habitat types by season.
1. Track count methods provide a parallel and detailed addition to existing visual survey data
4. Extractive safari use is compatible with sustainable wildlife community structure in the Kalahari, question is how to select off-take level? This info aids DPW decisions.
3. Hunting and viewing tourism does not change the basic plant structure.
High impact
Moderate impact
Low impact
Study Areas
Biltong, subsistence hunting permits
Springbok on non-extractive safari drive
Commercial Hunting
Agriculture, intensive human use
Linkage to existing data
University of Uppsala (Sweden) Visual surveys
(Wallgren Dissertation)
4-8% aerial survey Conducted annually
Visibility Correction Factor(VCF) will improve the Interpretation of data
Monthly Parks visual count Wildlife survey

Logistical needs for project
Johnny- Zsutswa
Masada - Ukwi
Grant support (of course) sought through Canadian and International sources
Data inspection for species of special interest. Movement, group size, adult: offspring ratios & time/area association with other surveyed species.
Lion (key management need)
Leopard (quota debate)
Aardwolf (sensitive species?)
Hyenas (2 sp)
Pangolin (recovering?)
Baboon (encroaching?)
Wildebeest (water dependent)
Cattle competition from wildlife
We only provide management recommendations (a) at the invitation of the management authority (DPW), and (b) with defensible supporting data.
Future Work
• The project is envisioned as a 2-phase project (2006-2009).
a. Track survey technique development w/ community members.
b. Survey techniques and employment to community members and game guards as a standard measurement protocol to involve them in resource management at grass roots level (2009-2012) & improve safari employment opportunities in KD1, KD2, & KTFP
