Twente, Nederland
Excursie Landschap Lezen: Organisatie door Ellen Genet - Presentatie en gids in het veld: Henry Hooghiemstra, paleo-ecoloog aan de UVA (Universiteit van Amsterdam)
River Dinkel and Dinkel Valley, nature reserve Lutterzand in De Lutte, the Netherlands - Province Twente. Erosion, wind and rain have created a whimsical pattern of natural sand sculptures in the sandy shore of the river. River Dinkel streams between the moraine of Ootmarsum and the moraine of Oldenzaal. It's an active, freely meandering river. Sediments that in the past 130.000 years were deposited by wind and rivers are broached again and deported by the Dinkel. In the Lutterzand Nature reserve, the Dinkel has cut in deeply in its own sediments, revealing several historic earth layers in its shores.

Henry zegt hierover: "- We zien een milde fase uit het Pleniglaciaal (32.000 jaar geleden),
- een landschap gedomineerd door riviertransport (29.000 jaar geleden),
- een landschap gedomineerd door windtransport (26.000-14.000 jaar geleden),
- de koudste fase van de laatste ijstijd (20.000 jaar geleden),
- effecten van de eerste opwarming na de laatste ijstijd (14.000-12.000 jaar geleden),
- een terugval naar bijna-ijstijdcondities in de Jonge Dryas periode (12.000-11.000 jaar geleden), - de start van onze huidige warme periode van het Holoceen met belangrijke bodemvorming;
- effecten van de beschadiging van het Middeleeuwse landschap door de mens waardoor stuifduinen ontstaan.

Juniperus communis - close up of male cones.
Juniperus vegetation in the Lutterzand, de Lutte, the Netherlands
Juniperus communis is a small coniferous evergreen tree or shrub, very variable in form, ranging from 10 m (33 ft)—rarely 16 m (52 ft)—tall to a low, often prostrate spreading shrub in exposed locations. It has needle-like leaves, green with a single white stomatal band on the inner surface. It is dioecious, with male and female cones, which are wind pollinated, on separate plants.
The fruit are berry-like cones, initially green, ripening in 18 months to purple-black with a blue waxy coating. The seeds are dispersed when birds eat the cones, digesting the fleshy scales and passing the hard, unwinged seeds in their droppings. The male cones are yellow, 2–3 mm (0.079–0.118 in) long, and fall soon after shedding their pollen in March–April.
Juniperus communis has the largest geographical range of any woody plant, with a circumpolar distribution throughout the cool temperate Northern Hemisphere from the Arctic south in mountains to around 30°N latitude in North America, Europe and Asia. Relict populations can be found in the Atlas Mountains of Africa (Source: Wikipedia)
