Hi Lorraine

Firstly thanks Mark, for elevating me to Doctor status - old John Skinner
would turn in his grave - always called me his most recalcitrant student.

I made an attempt to breed some caracal and serval in captivity some years
ago for release.  This was, however, more of a fun project than one having
any real conservation value.  Whatever the conditions are, which caused the
decline of the species in our area in the first place, are probably still in
place, meaning that a reintroduction would probably have been a waste of

The late Dr Andrew McKenzie did an intensive research program on jackal in
the NTGR in the eighties, concentrating on the 'Wild dog like pack hunting
Behaviour which the jackal exhibited here. I have a copy of his thesis
somewhere and will try and dig it up and see if he has any density estimates
  We find that the jackal population tends to swell to a certain level of
abundance and then crashes (often rabies is indicated in the crash) and then
swells again, and so on and so forth.

The DWNP records of skins and hides from the 70s and later, have been
misplaced in the main, but going to DWNP and instigating a search will help.
Tried to access them for some skins that were tagged, labelled etc to see if
a place of origin were recorded in the original data base which seems to be
difficult to find, so you need not bother going there. Maybe some of the old
hides and skins dealers will still have record books, will ask R.A. Bailey
for you, and see what records they have retained.
Traditional hunting permits permit  bat eared fox, caracal and black backed
jackal to be hunted, but dont think people need to report what they have
taken on thier permits.If they do, there may be some records there.DWNP
Jackal populations wax and wane, Ghantzi had many in 2009/ 2010, but rabies
seemed to have dealt them a blow, and they seem lower in population now, I
think these cycles are normal. Predation records( DWNP) mention them, and
Phd by Matthew Scwerner?? in Ghantzi ( Under Predator Conservation trust)
had interesting Jackal records, as jackal were seen to be a bigger threat to
livestock than wild dog as far as I can remember. Smallstock farming areas
like Tsabong may have more recorded problems than areas where cattle are
more important, so prob animal control records from there could help.
VEt Lab at Sebele will have recods of Jackal Rabies could be interesting to
see the cyclicity of the disease.
Leopard Ecology doing a long term camera trap survey, and have spoor
transect data for over 5 years, sure you can speak nicely to them. What did
camera trap survey on Tiisa and Oasis Farms come out with, very few caracal,
but I think the density of them is going to be low, the only place I see
them regularly is the makadigadi.What about the pHD thesis looking at spoor
on the transfrontier boundry, what is he finding??CCB also has camera traps
When are all these researchers who are doing really great work out there
going to sit around a table together??
With our stable large predator populations, we seem not to have needed to
actively hunt and kill jackal and caracal in Botswana like the farmers have
done in SA. We effectively have these populations under control, by means
other than farmers helping to create the South African super predator.
If the guides in the Delta had to maintain log books on key species, there
would be an amazing data bank of information to access.

Dear Lorraine,
I concur with Dereck. It is most unlikely that there are any realistic or
official figures for these or any other small mammals for the entire country
 Dr. Taolo from DWNP would be able to assist you there. The only work I know
that has been done on either of these species are: 1. Dr. Sam Kaunda from
University of Botswana who worked on B-B Jackals in the south (problem
animal study) and 2. Dr. Peter le Roux who did some aspect of caracal work
in the Tuli block - of what nature I am not that sure.
Extensive fieldwork is likely required to answer your question. Sorry about
All the best & good luck, Mark.

Hi all,
Would anyone have rough estimates of caracal and black backed jackal numbers
in Botswana. Are there any official figures?
