Contact informationThis poster was produced by Jess Neumann, Joanna Clark, Amanda Ingham (HIWWT) and Mark Barnett (EA) with input from others in the Loddon Project Team (Tom Breeze, Simon Mortimer, Gavin Parker, Geoff Griffiths, Simon Potts, Alison Bailey, Hannah Cloke, Liz Stephens, Anne Verhoef, David Macdonald and Barbara Percy from the University of Reading) and the Loddon Catchment Partnership. Funding was provided by a NERC Impact Accelerator Award for the project ‘Ecosystem Services for Catchment Planning in the Loddon Catchment’.

What is Natural Capital?

“The elements of nature that produce value (directly and indirectly) to people, such as the stock of forests, rivers, land, minerals and oceans. It includes the living aspects of nature (such as fish stocks) as well as the non-living

aspects (such as minerals and energy resources). Natural capital underpins all other types of capital… and is the foundation on which our economy, society and prosperity is built.” - The Natural Capital Committee (2014)

What is the Loddon Catchment?

The Loddon Catchment is the area of land (683

km2) that supplies water to the River Loddon.

Water from the River Loddon drains in to the River

Thames, which flows through London into the

North Sea.

Water transports sediments and dissolved

substances from both natural and artificial sources

as it moves through the catchment. The diversity

of vegetation, soils, geology and land use within a

catchment affects the pathway taken by water as it

is moves from rainfall through the land to the river.

These differences in the ‘water journey’ cause large

variations in the amount and quality of the water

between different locations. Therefore, natural

assets (or Natural Capital) are important to include

in catchment planning because they affect

ecosystem goods and services essential to support

human life, such as clean drinking water, flood and

drought regulation and food production.

Habitats & WildlifeHabitats and wildlife provide multiple benefits,

including food production, pollination, water

purification, and aesthetically enriching

landscapes. Each habitat supports a different

composition of wildlife. Habitats vary depending

on land use and local environmental conditions

controlled by soil, geology, slope and climate.

SoilsSoils store and release water and nutrients to

plants and animals, supporting habitats and

wildlife as well as regulating river flows, water

quality and the climate. The type of soil formed

depends on the interaction between geology,

slope, habitats, climate and land use.

Rocks & MineralsRocks provides essential minerals for a wide

range of everyday products. Some porous rocks

also store and filter a large percentage of water

that is required for drinking. The type of rock

affects the topography of the landscape (e.g.,

slopes), soil development, habitat type and

ultimately how water flows through the

landscape.

Rivers, Lakes & Ground

WaterWater is essential for life, providing multiple

benefits from drinking water to recreation.

Water is found almost everywhere to some

extent as it is continually moving through the

landscape from soils to groundwater,

concentrating as a water body in rivers and lakes.

The amount of water present in any one location

depends on the interaction between climate,

weather, habitats, soil, geology and slope.
