Counting elephants is not easy. It takes experience, skill, and funding. The good news: elephants are thriving in Namibia. Gail Thomson, veteran journalist, and conservationist delves into the incredibly complex process of elephant censuses.

Based on interviews with Kenneth /Uiseb, Debbie Gibson, and Colin Craig
The African savannah elephant was recently classified as Endangered[1] by the International Union for the Conservation of Nature (IUCN), citing a decline throughout Africa of 60% over the past 50 years. Yet in Namibia elephant numbers are increasing and their range is expanding; a testament to sound long-term conservation policies. But how do we know that they are increasing? How do you assess the status of an animal that ranges over thousands of square kilometers with any degree of confidence? I spoke to the experts to find out.

The small four-seater Cessna aircraft is full. The pilot is flying slowly in a dead straight line, maintaining an altitude of 300 feet above ground level. Behind him, two passengers stare intently out the windows; searching the ground between two black rods fixed to the plane’s wing struts. One passenger suddenly calls out: “left, elephant bulls, two,” followed shortly by the other: “right, elephant cows, ten in, five out.” The fourth person in the plane, sitting next to the pilot, decodes their cryptic messages and jots them down on a datasheet.

This is fine, and valid for savannah, and savannah elephant (loxodonta africana), valid census made by areal survey, in Namibia, and other countries with svannah habbitat.

However, this type of survey is imposssible for forest elephant (Loxodonta cyclotis) and their numbers are at best educated guess. True numbers of forest elephant are almost impossible to estimate. In forest, they are practically invisible and very hard to count.
 
also nearly impossible to spot loxodonta africana in thick bush or riverine vegetation, where they would usually be found in most countries
 
Awesome news about Namibian Elephants!

As for the other topic, there is a canopy penetrating scanning method using LiDAR I think. I learned about it years ago in a remote sensing/ observations class. It is use for surveying the ground or locating man made structures under heavy canopy. I wonder if it could be used to survey forest elephants?

I am again looking for 600 Nitro dies preferably RCBS 1 inch. The set I purchased previously are 1 1/2 inch and do not fit my die. Another member has graciously taken them off my hands. If anyone happens to have a set of 600 Nitro Dies that will fit my Rockchucker Supreme RCBS press, please shoot me a message and thanks in advance for any assistance you may have to offer!
I have not posted any items for sale on this forum and will not every put anything for sale. My account was hacked and I've worked with the admin to get things shut down.
