Animals and plants in natural settings must have minimal living regions in order to have sufficient room within which to live and survive. Because of global warming, it becomes even more important that plants and animals can migrant, otherwise they will die out.

However, if a natural region is too small, than it can be made livable through a connection with another ecosystem or biotope, via a so-called green corridor. Together animals and plants are then offered a chance to survive, beyond which can also initiate a similarly interesting landscape for human recreation. With the “Ecological Connection (EC)” is simply implied - a connection together with other biotopes.

What comes into existence then, in an Ecological Connection, is a newly created natural area: or natural developing regions. Natural developing regions are regions that must still be developed. There is also a transition form, mainly a region wherein farmers determine how convenants are made for looking after  and sparing nature. The water ways hold an important role: the big rivers, but also the small locks alongside arable land.

That nature is to be preserved is not to say that it has become realized or that this will happen in a short amount of time. Much can also happen in between, and as a consequence of economic pressure which is continually placed upon the plans and ultimately placed upon the available room for slowly consumed natural habitats.

It is also important to keep pollution outside of the EC. If the food in the EC becomes scarce or biodiversity decreases, the animals must seek food outside the EHS, whereby the chance becomes greater that they will become wrongly victimized or cause severe damage to crops.
