Now that, unfortunately, fires are once again occupying a large part of the news and the debate on forest management and prevention tasks is being revived, it is opportune to recommend a documentary series from Arte France that Canal 33 broadcasts on Monday evenings. You will also find it on the 3Cat platform (not very well labeled). It is titled L’arbre qui cache la forêt and has been translated into Catalan as L’arbre que amaga el bosc. In French, it plays on the expression equivalent to ours of “trees that do not let you see the forest.”The series starts from a very attractive premise, which affects the way of narrating more than the overall content. Each chapter starts with a historic and emblematic tree from a territory: the birch of the Great North, the thuja of the Great Pacific Northwest Rainforest, the giant eucalyptus of Australia, the baobab of Madagascar, the European oak, or the ceiba of the Amazon. The tree is the excuse to explain the entire forest ecosystem that is articulated around that majestic and centuries-old specimen chosen as the protagonist. As often happens in this type of productions, it is a relaxing and privileged window to observe the world. With the giant thuja, we travel to the west coast of Canada, to a forested area of sixty-four thousand square kilometers. With the birch, we discover the surface of more than one billion hectares of boreal forest that occupies the northernmost part of the planet.The tree that hides the forest is fascinating. It goes from making us observe the most minute details, focusing the lens on the most imperceptible spores or the insects that inhabit the trunk, to the contrast of the general plan, showing the tapestry that the treetops draw or the role of the salmon-filled river in nourishing the vegetation. The work of realization and photography is so careful (and perhaps a little too color-retouched) that the image ends up looking like one of those screen saver postcards that computers offer by default, which seem almost magical in their spectacularity. Locations that, due to their imposing vegetation and the solitude of the place, also have something sublime, of hidden mystery. The dubbing into Catalan is of great linguistic richness and lends the narration a slightly affected tone to force the poetic. You get used to it easily, even though the narrative intensity is a bit exaggerated. The story is added to by the testimony of experts in that corner of the world: biologists, ecologists, activists, sculptors, mycologists, and specialists in the most unheard-of disciplines that landscape can present. From any detail almost invisible to the human eye, a whole well of knowledge grows. It is fascinating to discover the influence that the tracks of millions of reindeer have on the shape of a forest and their impact on carbon capture. The series transcends trees in particular and the forests they portray to remind us of the complexity and importance of these ecosystems. Watching these documentaries makes you understand the tragic extent of fires and the little importance we give to forests.

In the historic Down House, the house where Charles Darwin lived for 40 years in Kent, England, there was a space that was key to developing the theory of evolution that would bring the English naturalist worldwide fame. And it's not the table where he wrote The Origin of Speciesbut rather his garden. There, Darwin spent hours conducting small experiments with plants, such as the so-called Darwin's orchid or Christmas orchid, from Madagascar. It is a very particular species, with an extraordinarily long nectary, over 20 centimeters. The scientist predicted the existence of an insect capable of reaching the hidden nectar. The butterfly would be discovered decades later, confirming an intuition based solely on botanical observation.
