Ecosystem services - I recently contributed illustration for the DEFRA Natural Environment White Paper, which is launched today. DEFRA - The Department for Environment, Food and Rural Affairs is a government department in the UK. You can download the Natural Environment White Paper here
www.defra.gov.uk/environment/natural/whitepaper/
The Natural Environment White Paper is a bold and ambitious statement outlining the Government’s vision for the natural environment over the next 50 years, backed up with practical action to deliver that ambition.
Nature is sometimes taken for granted and undervalued. But people cannot flourish without the benefits and services our natural environment provides. A healthy, properly functioning natural environment is the foundation of sustained economic growth, prospering communities and personal wellbeing.

I was thinking about National Parks shut down. How living in big cities affects us. And who should protect what in this country...

The San Pedro riparian area, containing about 40 miles of the upper San Pedro River, was designated by Congress as a National Conservation Area on November 18, 1988. The primary purpose for the designation is to protect and enhance the desert riparian ecosystem, a rare remnant of what was once an extensive network of similar riparian systems throughout the Southwest.
Many recreational opportunities are available within the NCA. Murray Springs Clovis Site, a significant archaeological site contains an undisturbed stratigraphic record of the past 40,000 years. Excavations were conducted by the University of Arizona from 1966 to 1971. People first arrived in this area 11,000 years ago. They belonged to what we now call the Clovis Culture and were the earliest known people to have inhabited North America. Named after the distinctive and beautifully crafted Clovis spear points they made, they were expert hunters of the large mammals of the last Ice Age. An interpretive trail leads visitors through the site. From Sierra Vista, take State Highway 90 east 6 miles to Monson Road. Turn left, and go about 1.2 miles to the signed turnoff to Murray Springs. The access road is located on the right.
The Spanish Presidio Santa Cruz de Terrenate is the most intact remaining example of a once-extensive network of similar presidios. These fortresses marked the northern extension of New Spain into the New World. Only a stone foundation and a few remaining adobe wall remnants mark the location of an isolated and dangerous military station. From Fairbank on Highway 82, drive approximately 2 miles west on Highway 82, turn right on the Kellar Ranch Road and travel approximately 3 miles to the trailhead. Hike about 2 miles to the ruins and interpretive displays.
The San Pedro House, located 9 miles east of Sierra Vista on State Highway 90, is a popular trailhead for birdwatchers, hikers, and mountain bikers. The Friends of San Pedro operate a bookstore and information center.

In the case of forest cover change, the studies refer to the period 1980–2000 and are based on national statistics, remote sensing, and, to a limited degree, expert opinion. In the case of land cover change resulting from degradation in drylands (desertification), the period is unspecified but inferred to be within the last half-century, and the major study was entirely based on expert opinion, with associated low certainty. Change in cultivated area is not shown.

While there are plenty of grunt to go around, the Gray Snapper rule the root system.
There are thousands to go around, including some real monsters, and most don't mind the occasional visitor to their realm.

Inland water systems are permanent water bodies inland from the coastal zone and areas whose properties and use are dominated by the permanent, seasonal, or intermittent occurrence of flooded conditions. Inland waters include rivers, lakes, floodplains, reservoirs, wetlands, and inland saline systems.

The pinyon pine and juniper ecosystem of the interior is adapted to regular wildfires, so this is a common sight.

The Sun's last light illuminates some high clouds over the grasslands of Tallgrass Prairie National Preserve. This preserve harbors 44 square kilometers of an ecosystem that once covered a million square kilometers and is almost all gone. This one shot is what I managed to get in my last dash into the preserve at the end of a 12+ hour drive. I had spent the morning photographing in Great Sand Dunes National Park in eastern Colorado, and didn't think I would make it there in time to photograph anything. As I got closer, I realized I might have a chance at a quick stop. I raced into the parking lot as the sun was setting, frantically inquired where I might go from the lone ranger who was leaving for the day and then set off in a spring with two cameras hanging from my neck and tripod in hand as I ran across the grassland minefield of buffalo droppings. This was the result of my sprint. The next day I had to carry on to the East and will have to one day come back and give the grassland its proper attention. It was neat to experience this tiny slice of this ecosystem, and it's interesting to imagine thousands of square miles of this in every direction with millions strong buffalo roaming wild in an extinct era.

A very simple ecosystem consist of moss, a blooming mushroom and some spider mites...
Any one can see the red legged mites?

Id updated.
we were reading "the ecosystem of a fallen tree" and decided to check out these, cut yes, but still dead logs for inhabitants
Maya brought her trusty magnifying glass and watched the ants
they were hoping to find a chipmunk with acorns in a burrow as seen in the book :D
but we did locate our 2 Oak Trees after I asked them where a chipmunk might find an acorn

Effects on ecosystem functioning
Mayflies are involved in both primary production and bioturbation. A study in laboratory simulated streams revealed that the mayfly genus Centroptilum increased the export of periphyton,[27] thus indirectly affecting primary production positively, which is an essential process for ecosystems. The mayfly can also reallocate and alter the nutrient availability in aquatic habitats through the process of bioturbation. By burrowing in the bottom of lakes and redistributing nutrients, mayflies indirectly regulate phytoplankton and epibenthic primary production.[28] Once burrowing to the bottom of the lake, mayfly nymphs begin to billow their respiratory gills. This motion creates current that carries food particles through the burrow and allows the nymph to filter feed. Other mayfly nymphs possess elaborate filter feeding mechanisms like that of the genus Isonychia. The nymph have forelegs that contain long bristle-like structures that have two rows of hairs. Interlocking hairs form the filter by which the insect traps food particles. The action of filter feeding has a small impact on water purification but an even larger impact on the convergence of small particulate matter into matter of a more complex form that goes on to benefit consumers later in the food chain.[29](Wikipedia)
