When Aotearoa was colonised, settler colonisers brought with them myriad species (rats, mustelids, cats, rabbits, possums) that have predated upon or outcompeted native birds. With habitat clearance for agriculture and residential development, this produced a contemporary in which over 51 native bird species are extinct, and over 75% of all remaining species are at risk of extinction. Many of these species are taonga (treasures) to Māori. Conservation efforts seek to protect those that are left, but certain methods are controversial, due in part to different understandings of the problem. Some see possums as a threat (to forest health, and, as vectors of bovine TB, to the agricultural sector) that should be removed by any means necessary; others, as a resource whose killing should be undertaken by trappers who can collect and sell their furs and gain honest work in doing so. Some believe conservation is a public good to be achieved using public money; others see it as a site for innovation, warranting private and philanthropic investment in biodiverse futures, perhaps even at the expense of nearer-term outcomes. 'Environmental governance' is now a patchwork enterprise shared between the state, state-owned enterprises, hundreds of volunteer groups, and private innovators and operators.

the floor of the valley has dropped in recent decades with increased groundwater pumping by farms, meaning more land might be subject to inundation,

Flood protection in California is largely a local affair, with water agencies, special districts and private companies building and maintaining the infrastructure. Smaller towns, like those in the San Joaquin Valley, often don’t have the money to develop their own levee systems, and while the state and federal government help out, winning investment from them isn’t easy.

The Tulare Lake basin also doesn’t have major Army Corps of Engineers flood projects to buffer large amounts of water as do some areas such as the Sacramento region.

The current crisis is the opposite of the usual one--instead of fighting over who gets access to water, groups are fighting over how to get rid of it.

Farmers, residents, municipal work crews, and hired contractors are reinforcing levees, pumping out excess water, and evacuating livestock, equipment, and homes.

One group was hired to protect a supply warehouse 3 miles south of Corcoran.

J.G. Boswell Company, which mainly produces cotton, owns most of the lowlands that are the Tulare Lake bed. They have allowed some fields to flood in efforts to protect other areas (the most productive farmland). The County Board of Supervisors forced them to cut another levee and flood more land because they weren't doing enough to protect populated areas.

Tulare lake used to be the largest body of water east of the Mississipppi. It had ports, steamships, elk and antelope. 40 different Yokut groups lived on its shores.
