National parks behind increase in wild-elephant population

Since wild elephants can only survive in national parks, and the area of non-human habitation has not increased, one would assume (if the report is true) that population density is increasing.
One potential area for this would be in the large national parks in Chiang Mai, Lampang and Chiang Rai, where a lot of the larger mammals were hunted to very low numbers or extinction decades ago. (Wild elephants do not relocate from forest to forest across tens of kilometres of farmland.)
More detailed information would be required to explain this claim. The article does mention Thung Yai Naresuan (Kanchanaburi) and Dong Phaya Yen (Khao Yai-Ta Phraya), areas with already healthy elephant populations, and it also mentions “reintroduction”, but does not go on to say more about this.
There are a significant number of large national parks that provide a safe and lovely habitat for these wild elephants. Kuiburi National Park is a good example. It presently has 237 wild elephants, and the population is growing by an average of 10 elephants a year. There are other success stories. Having spoken to some of the park rangers, they take their work very seriously and are very dedicated to the animals. It is nice to see that. They also have a lot of deer, herds of wild bulls, a few leopards, and bears.
