We only walked the quarter mile to Botswana's border patrol and then were picked up by a new vehicle (with more than enough seats) and drove into the bush to our camp. That night we were given a tour of the camp, shown the boundaries, informed on how we would be showering, and warned about the hyenas. The camp consisted of 6 tents and a bathroom in the volunteer area; a separate camp for the staff; and a common area where we ate, hung out between activities, and charged camera/kindle batteries.
The main activity we did in our week were censuses. We did at least one every day we were there, though every time we were at a different location (or hide). The first time our location was on top of a kopje (an isolated hill in a very flat area), where we sat and watched elephants, zebra, and a water buck for about 3 hours before heading home. We also had one census where all we did was try to identify birds (we weren't very good at that). And then another very special census that we did was an overnight in a hide which looked over a watering hole. We didn't see much that night, and we were very thankful to have the first two shifts, but it was very cool to sleep out in the bush underneath the full moon.
Our first manual labor activity that we had was road creation, where we spent a hot morning under the sun with pick axes, axes, a chainsaw, garden shears, and machetes taking down trees and clearing rocks from the path of the soon to be completed road. It sounds like the kind of activity that is the exact opposite of the reason we were there, but in creating a new road through the bush, they will be able to close off an old road, and allow the grasses to grow back.
The other manual labor activity that we did was fence removal, which sounds a lot easier than it actually was. Although that might have been more due to the conditions rather than the actual activity. The fence used to delineate the border between a farm and the private reserve we were working on, but after the reserve purchased the farm's property, the fence became a hazard to the animals there as they needed to be able to run freely without getting caught in the wire fence. The activity itself was us kneeling on the ground, bent over, untwisting wires from metal poles (about 12 per pole), and then moving the pole to a pile once all the wires were unattached. But then it was also hot. Really hot. We were informed it was 48.5°C (about 119°F) just before we left, and we got there about an hour and a half before sunset, so the flies in the area were going crazy to the point where there were hundreds surrounding each of us. Suffice it to say, we were very happy to go back to camp after that activity.
