The region of Lagoa de Óbidos Physical, Environmental and Climate

* Geology

Municipality of Caldas da Rainha has dominantly areas where the average slope is moderately steep with
situations in the area covered by the flat valley typhonic. The Municipality is composed of formations litilógicas conglomeratic sandstone, marly limestone and marl, still appear to affect the county formations known as sands,
sandstones and clays, red stoneware and some loaves of igneous rocks, in addition to mudslides.
The main geomorphological units are:

* Lagoa de Óbidos - of great environmental interest, considered the largest lagoon system and more
importantly the country.
* Escarpment (edge of the valley Typhon) - relief more important environmentally.
* High cliffs of the Serra do Bouro - a significant sea-front with high landscape and environmental.
* Beaches along the Lagoon,
* Flattened areas (Vale Typhon) -
* Embedded Valley - River Made
* Alluvial formations along the Bay of St. Martin - Salir do Porto.

* Flora

The gorse, heather and other species of indigenous vegetation cover the cliffs in its most inaccessible situations.
These species indicate their presence also in dune systems and areas along the coast, especially at the edges of
the valley Typhon is the massive limestone cliffs of the interior. One notes the presence of pine, pines, oaks, cork
trees and olive trees all over the County.

* Fauna

The fauna is mainly characterized by the abundance of bird species. There are areas of great interest
(under the convention that supports Portugal), consisting of biotopes of feeding, nesting and refuge for species:
- Made of Paúl: Wet Area of relatively wide area of great ecological significance and the county level.
It supports a rich and varied avifauna breeding population. This area also has some interest as a habitat to support post-nuptial
migration and vernal birds from North and Central Europe.

* Óbidos Lagoon: It is classified as a protected biotope: coastal lagoon in the surroundings of pine trees,
eucalyptus trees, reed beds and crops. It should be noted the Puddle of Ford, a small wetland with reeds.
Important area of production of bivalve molluscs and nesting Ardeidae, including Red Heron and Little Egret.
* Serra do Bouro: Zone of the rocky coastline, relatively isolated and with great geological interest and scenic,
supporting a characteristic avifauna rupicola. Place of regular occurrence of raptors, including the kestrel
and the Peregrine Falcon.
The abundance of fish species in the lagoon is relevant not only in the estuary and into the arms of the lagoon
as well as the waterways that flow into it and the adjacent coastline.

south of Nazareth. The Municipality is traversed in the direction NW-SE and the Ribeira de Alfeizerão Torne River,
tributaries of the Bay of St. Martin, and the sense E / W by Cal River, a tributary of the Óbidos lagoon.

Lagoa de Óbidos is a constantly evolving system whose life cycle has its origins in remote and low average age
beginnings of the modern age.

Their training will have given rise to the post glacial Flandrian, when the salt water penetrated the coast, giving
rise to many of the lagoons and coastal vacation Portuguese, and Óbidos Lagoon's largest territory.

It was however already much bigger than it is today.

The maximum extension was achieved for nearly 5000 years and remained virtually unchanged right until about
2000 years ago.

In late Neolithic of the waters of the lagoon reached broadly the area where today is the village of Óbidos
and structures such as the A8 motorway.

Between 1987 and 1995 the contours of the pond suffered significant changes toward the diminution of its area.

The natural process of sedimentation and the influences of human activity are the main factors shaping this
development.

Today is an important site for the local population, by socio-economic opportunities it provides
is also much sought after for its beaches which are separated by the bar and it is known locally as "Aberta."
What is the place for communication and passage of water between the lagoon and the Atlantic Ocean.
