Governmental policy surrounding endangered species changes, indicating that the population’s perspective has changed. Legal rights have changed due to shifts in moral responsibilities.

This is the Tasmanian Coat of Arms, featuring two thylacines. This is representative of the change in perspective that has occurred, as the animal is now revered instead of loathed.

Tasmanian Government, Tasmanian Coat of Arms, 1917 

“Subject to subsections (2) and (3) , a person must not knowingly, without a permit –
(a) take, keep, trade in or process any specimen of a listed taxon of flora or fauna; or
(b) disturb any specimen of a listed taxon of flora or fauna found on land subject to an interim protection order; or
(c) disturb any specimen of a listed taxon of flora or fauna contrary to a land management agreement; or
(d) disturb any specimen of a listed taxon of flora or fauna that is subject to a conservation covenant entered into under Part 5 of the Nature Conservation Act 2002 ; or
(e) abandon or release any specimen of a listed taxon of flora or fauna into the wild.” (Threatened)
This section of the Threatened Species Protection Act demonstrates the more recent policy surrounding endangered species in Tasmania. These listed policies are all in the effort of conservation, and were also made by the state. This shows stark development in the government's role in Tasmania, contrasting their previously discussed bounty system.

“For more than a century, devils were trapped and poisoned and they became very rare, seemingly headed for extinction. But the population gradually increased after they were protected by law in June 1941.” (Save)
A quote from the Save the Tasmanian Devil Program, showing that after legal rights changed, so did the population, and therefore that laws were an important factor in the conservation of this species. 

Is there perhaps a thematically named modern example of this newfound conservation mentality?
