 Exploration of trees in the city of Brussels (1000)
-  * Introduction to the juridic context & management of trees and parks
+**  * Introduction to the juridic context & management of trees and parks**
 It is complicated :-)
 These public trees can belong to different official owners: the city, the Region (regional roads & parks), the king, the federal state. This is the first thing to find out.
-All trees in protected parks are also protected:
+All trees in protected parks are also protected: Parc ROyal, Egmontpark, Leopoldpark, Sq Marie-Louise, Sq Ambiorix, Kleine Zavel (belongs to Region), Vrijheidsplein, Barricadenplein.
 The trees in Regional parks and on Regional roads are signed with a number.
-The trees in the city of Brussels have only been registered since 2008. In 2011 they started an inventory of all trees in 1000 Brussels. It is not finished yet. The rumour goes there are about 40000 different trees.
+The newly planted trees in the city of Brussels have only been registered since 2008. In 2011 the city started an (non-publicly accessible) inventory of all trees in 1000 Brussels. It is not finished yet. The rumour goes there are about 40000 different trees.
+The Region has set up a public database on 'remarkable' trees: [[http://www.arbres-inventaire.irisnet.be|inventaire arbres]]. A tree can be part of the scientific database (it corresponds to the selection criteria), the conservation list (bewaarlijst: the tree cannot be cut or treated more than normal maintenance without permission of the state) or on the protected list (idem bewaarlijst + when the tree dies, a tree of the same species has to be planted in the same location).
+Selection criteria are: a considerable trunk (at 1,5m), the localisation (the more visible for the more people, more remarkable), the frequency (less frequent, more remarkable), the historical value (referenced in literary and other works), the age, the individualisation (in group, less remarkable) etc.
+The team of the 'Cel Groene Zones' of the city of Brussels has selection criteria to chose trees to plant. The trees are 'suitable for urban environments' when:
+  * their roots resist salt (in winter)
+  * they resist pollution (cars/busses)
+  * they resist litter & vandalism (when you break a branch of a fruit tree it will not survive)
+  * they can stand presence of humans at their roots (a walnut tree needs rest at the roots for the first 15y of its life, treading the soil condenses the soil and puts pressure on the roots)
+  * they are easy to maintain and don't cause too much trouble for inhabitants (leafs that fall off, block the sewage etc)
+Trees that are frequently planted: plataan, ash, lime tree, hazel, hawthorn
+Another criteria that is on stake for trees in the city: the presence of sewage, waterinfrastructure, gastubes or electircity cables in the underground, f.ex. there are no trees in Rue Dansaert, which is an important ax)
+**  * exploration city**
+//Walk in the city center//, looking at trees, what they provide us with, how we could ent them
+Final destination: Prutske, the fig tree at La Bourse that is present in the scientific database of Monuments and Landscapes
+Discovery: the mini-oasis of biodiversity on Pantsertroepensquare, that has a 'bad' reputation as a dirty gipsy park
+trees are more difficult to identify because they have not blossomed yet and the maintenance has eliminated leaves, fruits or other identifiers...
+amazing how little grass and paths are left in the city, we guess it has also to do with maintenance and tidiness
-  *
+//Walk in the city forest//: park of Laken where trees are like 'furniture for humans', discovery of a group of yews, shaking the branches produces a cloud of dust (pollen), female next to male trees; some numbered trees (check!)and a series of traces of which we are not sure whether they are from humans or from animals (wild chestnuts, leaves, chicken bones, rests of a walnut)
-exploratie stad
-inleiding tot juridische context & beheer van bomen en domeinen (Belgische politieke systeem, geklasseerde bomen en parken door Gewest, Monumenten en Landschappen + Gewestwegen + koninklijke domeinen → voor volgende keer: een lijst), criteria om een stadsboom te planten (zie blauw boekje)
-opzoeking geklasseerde bomen centrum www.arbres-inventaire.irisnet.be
-wandeling door de stad, welke bomen, wat geven ze ons, hoe kunnen we ze enten, met wat, om een imaginaire boom te maken: ontdekking van rijke diversiteit op Pantsertroepensquare, je zou er bijna kunnen leven, ze bieden schaduw aan gypsy's in de zomer
-plukken van gedroogde vijgen aan de Beurs / geen bomen in de Dansaertstr
-lunch
-exploratie 'stadswoud': park van laken waar bomen meer meubels zijn voor mensen, ontdekking van venijnbomen (in serie) die stof afgeven, de vrouwtjes; van genummerde bomen (check!) en van de onnoembare mens-diersporen (ze lopen hier door elkaar, vb kippenstrotje & wilde kastanjes, rest van okkernoot – murderstory)
