The idea of ecosystem services is appealing to land ecologists. It promises a new way to convey the value of ecosystems and ecological processes to a broad audience and focus attention on sustainable management of those services. While this effort gives monetary value to what many of us have only been able to describe in terms of the passion we have for the workings of nature, quantifying ecosystem services to the point where they can be ‘monetized’ is a step or two beyond what most of us had in mind when we entered the profession. Yet, if we are serious about communicating the value of

A steady stream of news articles announce: “Desertification affects (insert fraction) of (insert country)”. A photograph of a sand-engulfed house, dry riverbed, dead animal, or close-up of cracked earth accompanies the story. Environmental catastrophes make for interesting reading. But it is seldom clear what ecological phenomena the term “desertification” actually refers to, and therefore what the solution might be. And it’s the solution that matters.

The future of Mongolian rangelands is at a crossroads. The decision is whether to try to control livestock numbers or to allow (or encourage) numbers to increase. Many believe that the latter will result in irreversible changes, including those called ‘desertification’.

Twenty years ago I completed my Master’s work in the Chaco forests of northern Argentina. The native forests are, in fact, rangelands. In addition to livestock production, the forests are used for timber extraction and wildlife harvest (think tegu lizard cowboy boots). I took part in a project comparing biodiversity among production systems. A new system promised to reverse biodiversity loss and soil degradation. But it’s a moot point now since many of those forests have been cleared for cropland--the highest rate of tropical forest loss in the world.

I recently visited Santa Fe with some friends. When we go there, we always seem to wind up at the Georgia O’Keeffe Museum. Although most widely known as a pioneer of American Modernism and for her large format paintings of blossoms, she also revolutionized the way people viewed landscapes, especially New Mexico landscapes. Many tourist guides now refer to the landscapes of northern New Mexico as ‘O’Keeffe Country’. One of the popular exhibits mounted in the last decade is titled ‘

The path toward environmental sustainability and ecological resilience starts with maps. Different land areas present different risks and opportunities, so we need to be able to classify those land areas and know where the classes occur. One new approach to this task fuses soil science and vegetation ecology by linking digital soil mapping (DSM) to state-and-transition models (STMs).

Last week, an agricultural researcher from the Monte Desert in Argentina emailed me to put him in contact with a seed supplier in the US. They wanted seeds of the perennial grasses blue grama and Lehmann lovegrass for some revegetation trials. I wanted to hit reply with: ¡Por favor, no lo hagas! (don’t do it).

The U.S. Fish and Wildlife Service just proposed to list as ‘threatened’ the Lesser Prairie Chicken throughout much of the high plains region based on a precipitous decline over the past 10-15 years. This shouldn’t have happened.

As graduate students, some of us entertained the hope that our science would trickle down from the ivory tower and inoculate land managers with the seeds of broader vision and better practices. That seldom happened. Over the last decade+ since, there has been a lot of hand-wringing about the science-management interface. In the 1990s, I recall that “applied” ecology was met with thinly-veiled disdain from members of the ecological science establishment.
