Gentbos, Herfstwandeling 22.10.2016

This was an organized walk by the Vogel Aziel Merelbeke.

Attention was paid to the different fungi, as can be seen on my pictures later on in this post.

Aardappelbovist and inside it there are green spores.

We heard a boomklever which, according to the guide and to his surprise, is singing its spring song. Weird. X

The guide points out the non native American oak can have 100 insects living on it, but that a similar native oak could have up to 500 insects living on it. This is because the American one is not as well adapted to the conditions here. In addition, the leaves are too thick and strong and take a long time before they are composted. In the meantime, they do not let any light or life through them and suffocate the forest floor. But, this tree is doing very well here. He also points out that the maples are half shadow trees and are doing okay here.  However, another guide has told me that the Gentbos maples are almost all sick. X

He also points out as we pass by the big fallen American oaks, that when trees are felled, it´s important to pay attention to the surroundings, such as, from where will the wind come, as the changed environment can have surprising effects on the area after trees have been felled, e.g. with increased wind, some trees can spontaneously fall down.

He talks about which kind of mammals are to be seen in this forest. He mentions that  dears are coming back and so are martens, stoats, weasels and foxes, though the latter ones haven´t been away even.

Other fungi we saw include gele koraalzwam, reuzenzwam, schubbige bundelzwam, houtskoolknotzwam.




Gentbos, 6.9.2016

We see an aardappel bovist. The reuzenzwam that is rare, is doing well on one of the fallen trees. Luckily this fungi is tucked away from the people, it would otherwise be cut out. Can become very large, the size of my butt. We are looking at the difference between tamme and wilde kastanjes (difference can be seen in leaves as well as the chestnuts). We wonder why the daalkruid is in BE an indicator of old forests, can it have to do with sour grounds? X In FI it´s mostly the species that first blooms, thus a sign of spring, and mot definitely not to be found in old growth forests, but from deciduous groves.

We see a nest that looks first like a hornet´s nest but turns out is a birds nest. I later on look it up and it looks to be a boomklever´s nest as it sometimes makes its nest in old woodpecker´s nests and makes the doorway smaller by spreading clay around it. I get the same diagnosis from a couple of forest knowers.


Gentbos, 2.9.2016

Dry path, with grass growing on it. Imagine that this path is totally muddy in the winter. I can hear the geese from the pond on the terrain close by. My creek looks very dry. Only very little water, leaves are falling – because of drought? Grasses are all white at the edge of the stream. There´s been about 0.5 meters difference in how high and low the stream rises.

Gentbos, 11.3.2016

Something´s flying in the sky, we hear it´s sound and we see the wings have white stripes on the top as it moves. We know it is a buteo buteo, hiirihaukka. The ground is covered with frost, the mud is solid but not completely. We hear and see jackdaws, blackbirds,red robins and great tits. In the creek, dark hummus layer has settled at the bottom, water is clear. The deepest part seems to have moved after the turn. Speenkruid is blooming with yellow flowers already on the side of the creek where the sun hits! Nettles are raising their heads. I am wondering whether the hazel next to my creek has been a hakhoutstoof. Looks like it. It is not yet making any start of blooming. Hondsroos seems to have leaves already. I hear a bird sing and think i know which one it is. I play it on my book of bird songs (comes with recordings) and immediately the bird in the forest answers. It is metsäkirvinen.

Gentbos, 2.12.2015

A lot more water than last time in my creek. Seems like water has risen up because plants are pressed down. Or maybe heavy rain and wind from last week? There´s some foam in the place where the creek makes a turn. Because of high speed and lots of oxygen? X

Stream has made some branches lose. Also  big branch fallen in the middle of the path.

The muddiness forces people to find drier paths, and this breaks the soil floor even further.

Gentbos, 27.11.2015

I see most more moss growing at the bottom of threes here than in Finland. Is that because of the humid air? There is laddermos. X

Veel vogels in the struiken wan meidoorn, sleedoorn, hondsroos omdat er besjes zijn. Knoppen in de bomen al in de herfst – wat als het nu heel koud wordt? X

Elfenbank, tonderzwam op hout.

Pheasant is calling.

Why are the roots of the esdoorn growing on top of ground?  X

Verse mol hoopjes.

Some plants are still not wilted, such as speenkruid, hondstraf, fern.

The creek is streaming fast, or maybe it looks like it because there is a lot of material in the stream. There´s also foam in the water. I wonder why? X

I see a judas oor on the vlier. There´s a place where an uil has eaten a duif. The insides of the stomach are still visible (corn). Braakballekes. It´s always around the same place where I see this. The territory of the uil (which uil)?

The kastanje is a windbestuiver en the katjes are our in the beginning of the year so that they get blown away before the very big leaves stand in the way.


Gentbos, 18.10.2015

Partly cloudly, no wind, about 13 degrees. It is 15.58.

Red robin singing at the parking in a leafeless tree. A flock of bird took off as they heard us. Also heard the geese, the ducks and the donkey at the pasture.

The colors are dried out green, some red at the top leaves. The oak on the meadow has dropped a lot of it´s nuts but is only partly yellow.

The mud is solid. I hear children screaming, there are a lot of people. Mushroom with a white rim. I hear the oak nuts falling on the ground.

Ferns are turning yellow and also wood sorrel.

I see a big dead tree.



Grasses on the bank of the ditch are getting yellow.

Nettles on the field are black.

Mushrooms inside tree trunks, berries, leaves starting to turn, majority still green. Other mushrooms as well. Red catchfly/campion (Koekoeksbloem) is blooming next to the corn field. Moss on the branches of elderberry. Hop growing on trees.

Gentbos, Wed, 4.11.2016

Met L & N

het weer: 13 graden, zacht wind, af en toe klein beetje regen

Deze keer heb ik geen fotos. Batterij plat!

Linda’s vraag: waarom wordt een blad van een boom bruin/rod/oranje in de herfst?

= de groen in de bladeren (chlorophyll) is voeding voor de boom tijdens daglicht. In de koude maanden, de bomen groeien niet maar zijn aan het “slapen”, en laten de bladeren vallen. Maar voor dat, nemen ze de chlorophyll in de boomstam. Als de bladeren geven de chrolophyll weg, veranderen ze van kleur.

Linda’s vraag: wat is de rol van beuk in het algemeen/in Gentbos?

=beuk is gebruikt voor de harde hout (parketten, meubels). in de gentbos de beuken waren geplant en nu gaan ze proberen om sommige van ze om weg te doen om meer plaats/licht te geven aan de zomereik en gewone es (

Linda’s vraag: waarom veranderen ze van voeding tijdens de winter (van insecten naar zaadjes)?-

= omdat ze zijn een beetje mixed eters (er zijn geen insecten tijdens de winter dus gelukkig kunnen zij ook zaadjes verteren)?
