The Lighter Side of Life – Rewilding 


April 2023


Our society’s general acceptance of the need for economic growth and the requirement of functional natural ecosystem for human health are in serious competition – which is becoming more evident in clinical medicine and public health. 

I would like to share with you some ideas which I believe in. Ideas which can be done as an individual, but which would have great impact if executed in a strategic and collaborative fashion.

In the surgical world I am considered as a generalist; practicing on a relatively broad spectrum of traumatology. In reality, I’m a specialist  focusing on one species and one disease; injured humans. My attempts to keep focused on the bigger picture led me to rewilding.

'Rewilding' is a controversial word but my definition for it is: ‘to leave natural environments be’. Nature will restore itself through trophic systems (food webs) if we protect keystone species – frequently top predators. My definition does not include invasive human interventions, radio collars, tranquiliser shots, creating fake schemes for carbon credits with mass planting of fast-growing non-Indigenous tree species, or biodynamic farming. 

While government actions in sustainability are frequently questionable, we live in a country where 70 per cent of the land is in private ownership. This gives us a huge opportunity and responsibility. Our earth requires about 30 per cent of it's land, inland water and coastal water mass to be preserved or restored into their natural state to sustain long term human co-existence. The government in either not willing to do it, or cannot do it with the proportion of private land ownership. Taking control of this initiative as individual land owners is as important as responsible management of operating room ‘waste recycling’, which is imperfect at best. 

Here, I will share with you three examples of projects I am involved in which, I feel, meets the criteria for true rewilding progress. 

The Northern Jaguar Project

The Mexican state of Sonora is the northernmost current natural range of the jaguar (Panthera onca). Here, we are supporting the acquisition of contiguous cattle farms and turning them into jaguar habitat. The Northern Jaguar Reserve and Northern Jaguar Project was established, but this sizeable land cannot function as jaguar habitat without the collaboration of the adjoining cattle farms. The jaguars historically were killed here by contracted bounty hunters for 5,000 pesos (approx. $415AUD) each to protect the cattle. The neighbouring landowners were invited to join the project by signing a memorandum that they won’t kill jaguars and won’t hunt their prey (deer, capybara, etc.). In return, their farms were equipped with camera traps.

Every camera trap sighting of a jaguar credits exactly 5000 pesos to the landowner and they have the naming right for the newly sighted jaguar. Three pictures a year is enough to provide feed for the cattle in a bad year. The local farmers quickly worked out that one jaguar can make many times over the 5000 pesos if they do not get shot. By naming individual jaguars after family members the chance of an assassination became even less likely! The land has just enough game to maintain the jaguars in balance, which the farmers recognised in retrospect; “every time I shot a deer, soon I lost a calf from predation”. Saving their natural prey helped makes the jaguar uninterested in cattle. Focusing on the preservation of the apex predator’s habitat also had a huge positive downstream effect on four other wild cat populations (puma, bobcat, ocelot and jaguarondi) and the rest of the flora and fauna of this 56,000 acre reserve. An example of how focusing on the keystone species benefits all wildlife. 


WildPlains
WildPlains (Wild Plains Conservation Project) is a small central European grassland and wetland reserve, which was established as a buffer zone for the adjacent national park from marginal agricultural land of miserable yield with excessive fertilisation and pesticide use. After the abandonment of farming and the introduction ultra-low intensity grazing with the proxies of the extinct megafauna, the land bounced back in biodiversity providing habitat for many species not seen for a long time and allowed the documentation of 219 bird species.

COBRA
COBRA (Curricabark Open air Biodiversity Restoration laboraAtory) is a recently established reserve for perpetuity and approved by the Biodiversity Conservation Trust. It was cleared about 150 years ago and had been grazed ever since. It’s new role is to provide a wildlife corridor between two national parks and a refuge to the endangered brush-tailed rock wallaby (Petrogale penicillata), which is not as well-known marsupial as the koala, but just as endangered as we have only about half as many of them left in the wild. The project also serves as a training site for the traditional custodians of the land for cultural burning practices to teach future generations. Watch the 'Cultural Burning at Curricabark: Walking together in conservation' video for more information on this cultural burn workshop and how it improves habitat conditions for native fauna.

Depending on your ability, you can make your activity smaller by turning your courtyard into an indigenous micro-forest or acquire up to two per cent of the landmass of Chile and donate it to the government through Tompkins Conservation but the concept is the same: active, individual, measurable impact towards the preservation of our natural world.
