This has caused increased flooding and sedimentation, ending peat formation in the delta.
2.
The process of thick peat formation takes millennia.
3.
This led to an increase in peat formation and probably the abandonment of many upland settlements.
4.
Oxygen deficiencies and high acidity in the constantly moist substrate inhibited the decomposition of dead plant parts and led to peat formation.
5.
In order to understand peat formation by mangroves, it is important to understand the conditions they grew in, and how they decayed.
6.
Thorne Moor showed evidence of faunal activity prior to the peat formation, as part of soils able to support deciduous woodland, prior to peat growth.
7.
BC is the earliest available on Hatfield Moor for wetland inception and indicated the northern part of Hatfield Moor was one of the earliest foci for peat formation.
8.
Peat formation, a product of high plant productivity, was reestablished only in the gymnosperm forests appeared earlier ( in the Early Spathian ), but again only in northern and southern higher latitudes.
9.
Although sea level changes since the Pliocene led to changes in sea level and the laying down of vegetation, the peak of the peat formation took place in swamp conditions around 6, 000 years ago, although in some areas it continued into medieval times.
10.
Where steep slopes have inhibited peat formation, the blanket mire gives way to dry heath, in which heather, wavy hair-grass, " Deschampsia flexuosa ", and bilberry, " Vaccinium myrtillus ", are the dominant species.
