Corona springtime; nature gives and takes

Right now, especially in these turbulent times. We’ve all heard the cliché a thousand times over the past few weeks of lockdown, quarantaine and social distancing. And yet I will use it once again: particularly during this difficult time, nature can offer us comfort, hope and inspiration. Home To be honest, I don’t have that much to complain about my own situation. I have always worked at home and I don’t suddenly have to deal with children who I have to teach or who drive me crazy in other ways. There are undoubtedly better, but also much worse, places to...

A Virtual Forest and One Trillion Real Trees

The World Map of Trees, shown below, is made of more than 15,000 trees that together form the continents of our planet, while the surrounding grassy meadows represent the oceans. A piece of land art on an area of approximately 200 hectares, accessed by roads and paths (the equator and some meridians) and with ditches representing tropics and polar circles. All this of course entirely digital and virtual, because unfortunately I have no backyard of this size. Apart from the fact that this forest map is a nice addition to my collection of world maps (see, for example, the stained...

Autumn in Rotterdam: a Tree Tour

I hardly have to tell the reader why it’s good to have trees in the city. They purify the air, they absord CO2, they make it slightly less hot in the summertime and they retain water after heavy rain showers. And of course they also make things more beautiful. This decorative function is most obvious in two periods: spring and autumn. Trees that in previous months were fairly inconspicuously bare or green, suddenly burst out into a feast of color. Now that the meteorological (and photographic) fall is over, this blogpost aims to give a small, totally incomplete, tour of...

The Hydraulic Forest in Autumn

The Waterloopbos (let’s translate that with Hydraulic Forest) in the Dutch North East Polder has a post-apocalyptic quality. It is as if a nuclear disaster occurred here fifty years ago. Everywhere you see crumbling wall, sluices, canals and strange installations, partly overgrown by the forest. Hydraulic engineering The reality is, fortunately, somewhat less dramatic. From 1952 to 1995 this area was in use by the national Hydraulic Laboratory. The numerous watercourses and ponds with their wondrous artifacts are the remains of hydraulic scale models. The area is nowadays a national monument and open to the public. November This summer I...

The Lijnbaan Plane Tree Needs Your Vote!

I live in the center of a big city and yet only fifty meters from the Tree of the Year. Or, well, one of the nominees for the Dutch Tree of the Year election 2019 . Giant This tree, the famous Lijnbaan Plane Tree, the tree that has seen it all, has been nominated as a candidate for the province of South Holland. The 168-year-old giant is so large that I had to paste six photos together to get this full picture of it. Eye witness It is a tree that has a story to tell. A tree that has...

Liquidambar Styraciflua, in Other Words: the Sweet Gum Tree

Oddly enough, I never really noticed them until the autumn of last year and now I suddenly see them everywhere: sweet gum trees or liquidambar styraciflua. Time for a photographic tribute to the mother of all autumn trees. America The amber tree originates from the southeast of the United States, roughly from the New York – Houston – Orlando triangle. In addition styraciflua grows in higher altitudes in Central America. Chewing gum tree The English language has a lot of names for the liquidambar styraciflua. Quoting Wikipedia: American sweetgum or simply sweet gum tree, American storax, hazel pine, bilted, redgum, satin-walnut,...

Springtime in Rotterdam: Magnolia, Prunus, Robinia

For some photos the window of opportunity is very small. You have to be quick, otherwise your chance is over. Think, for example, of the increasingly rare photos of the city under a nice layer of snow. Or photos taken in the blue hour after sunset, when the circumstances change by the minute. Spring is another of those narrow windows. One moment the trees are still bare, a few days later they are full of blossoms and/or young leaves. And if you don’t act promptly, the spectacle is already over by the time you get your camera. Late Spring was a...

Flowering Cherries in Rotterdam

Trees in the city, I love ‘m. But I’d love a little variation as well. In Rotterdam there are so many plane trees that even I, traditionally a big plane tree fan, get a little bored. But fortunately sometimes a different species is chosen, and how beautiful that can be seen at Van Oldenbarneveltplaats. Since a few days the flowering cherries there are in bloom. The experts are not yet sure whether they’re Prunus Avium or Prunus Serrulata. One week each year It is a pity that the stunning beauty lasts only a week, but hey, that’s nature. And that...

Ten Years of Digital Photography

Ten years ago I bought my first digital camera, a Canon Ixus400. A good reason to reorganize my Flickr photostream, to make a nice selection from the 30.000 pictures I’ve made since then. The last time I checked, Flickr had a maximum of 200 pictures on a free account; allright, then I just had to pick the 200 very very best ones. Strict criteria In order to make that large number manageable, I identified a number of themes that keep recurring in my work: trees, islands, paths and trails, reflections and shadows, and a dozen others. From each theme only...

Greening Aert van Nes

Aert van Nesstraat is a rather stony street in the center of Rotterdam. There are some interesting buildings: the pre-war Atlanta hotel and some monuments from the post-war reconstruction era like the Lijnbaan and the Bank Mees and Hope. And okay, a few architectural blunders from the seventies: the parking garage of the Bijenkorf and the so-called Rotterdam Building. But what’s especially remarkable is the total absence of green. Admittedly, the western part of the road runs along one of the Lijnbaan courts. But in the section between Lijnbaan and Coolsingel there is not a tree, not a bush, not...
