No way!Arnold van Vliethttps://www.globe.gov/en/c/message_boards/find_message?p_l_id=18703103&messageId=370809752018-01-11T19:04:52Z2018-01-11T19:04:52ZDear all,<br />We experienced record early start of flowering of hazel in the Netherlands. In a previous post I already told that the first hazel trees were very early. Now it is clear that the peak of the first flowering observations (the date when half of all hazel first flower observations have been sent in) took place before New Year! This never happened before in the Netherlands. 50 years ago the average peak flowering date was 15 February! <br /><br />The most important reason for this record is the very high temperatures since October. The average temperature from October, November and December has been 8.5 degrees Celsius. 50 years ago that was 6.3 degrees, so more than 2 degrees Celsius higher this year. Only 2014, 2015 and 2006 had a higher temperature in these months. Different this year was that September has been relatively cold which could have triggered the trees that winter was approaching. Then the temperatures increased and the trees 'thought' spring was coming. An exiting start of the growing season in the Netherlands. Temperatures in January so far are still 2.2 degrees Celsius above normal. Last week the first daffodils started to flower! I was asked to explain the situation in front of the cameras of the main Dutch news channels.<br /><br />I'm looking forward to what this year will bring with the GrowApp! <br /><br />I wish you all a nice GrowApp year with the creation of beautiful and scientific relevant time-lapse videos!<br /><br />Arnold van Vliet, Wageningen University, the NetherlandsArnold van Vliet2018-01-11T19:04:52ZPollen Allergies in winter? No way!Bára Semerákováhttps://www.globe.gov/en/c/message_boards/find_message?p_l_id=18703103&messageId=370755952018-01-11T15:39:49Z2018-01-11T15:38:45ZYou may wonder what makes me talk about allergies in January. Trees start flowering in spring, everyone knows that, so why to be alerted now?<br /> <br />Listen to what the phenologist Lenka Hájková from Hydrometeorological Institute says about the onset of pollen episodes for this year:<br /> <br /><em>“This winter air temperatures are so far 2 °C higher when compared to the long-term average. The forecast for following week only confirms that nothing much will change about the fact that we experience yet another warm winter, or more precisely: high-above-average-warm first half of winter.</em><br /><em>The mild winter results in an early onset of flowering of hazel trees, and if the temperatures do not drop below zero soon, we can expect the alder tree to start flowering as well. Hazel and alder trees belong to the significant source of pollen allergens and what is even worse, these two are easy to wake up from winter slumber. Look at the hazel. The tree needs only couple of days with temperatures above zero to form the buds of male flowers that afterwards quickly progress to swelling, bud burst and flowering phase. Then you can observe bunches of hanging yellow flowers, with clearly visible anthers that release pollen.”</em><br /> <br />That was a report for Czech Republic. What about hazels in your garden?<br /><br /><ul><li>Take a picture of a hazel tree with Grow App and add one more detail photo of the flowers. Don´t forget to keep a handkerchief in your pocket if you suffer from allergies! ;-)</li></ul> <br />The message for today:<br /><strong>NEVER STOP OBSERVING TREES. ALTHOUGH THEY SEEM TO BE DEEP ASLEEP, THEY CAN WAKE UP FAST.</strong><br /><br />And if you missed it, read the comment of Arnold van Vliet who spotted flowers of hazels in Netherlands even before Christmas:<br /><a href="https://www.globe.gov/web/european-phenology-campaign/overview/discussion-forums/-/message_boards/message/36437345">https://www.globe.gov/web/european-phenology-campaign/overview/discussion-forums/-/message_boards/message/36437345<br /></a><img src="https://images.e-vision.nl/naturetoday/images/optimized/6bca3a69-f446-41ac-9f2c-e33a20d5523c.JPG&h=350&w=870&v=1512842132" /><a href="https://www.globe.gov/web/european-phenology-campaign/overview/discussion-forums/-/message_boards/message/36437345"></a>Bára Semeráková2018-01-11T15:38:45ZWinners of Best Animation: September, October and NovemberBára Semerákováhttps://www.globe.gov/en/c/message_boards/find_message?p_l_id=18703103&messageId=364837872017-12-12T10:12:47Z2017-12-12T09:53:05ZCongratulations to the teachers and students from following schools, who are awarded for the Best Animation of the Autumn Campaign:<br /><br /><strong>SEPTEMBER:</strong><br />School:<strong> ZS Manesova Otrokovice, Czech Republic</strong><br />Birch tree animation with more than 100 pictures in row!<br /><a href="https://phenology.geodan.nl/uploads/fbe704b6ea1606e557dccbe31617fd66.gif">https://phenology.geodan.nl/uploads/fbe704b6ea1606e557dccbe31617fd66.gif</a><strong></strong><br /><br /><br /><strong>OCTOBER:</strong><br /><strong>Königliches Athenäum Eupen (KAE) Eupen, Belgium<br /></strong>A school with more than 25 different animations taken by students!

Last week I saw my first hazel trees starting to flower. This is very early and it is snowing! Yesterday I publised a news story on Nature Today (<a href="https://www.naturetoday.com/intl/nl/nature-reports/message/?msg=23984">currently only in Dutch</a>) which was picked up by many newspapers and this morning I gave a live interview on one of the national radio channels. It looks like that people that who are sensitive to pollen of Hazel will experience hay fever symptoms during Christmas. <br /><img src="https://images.e-vision.nl/naturetoday/images/optimized/6bca3a69-f446-41ac-9f2c-e33a20d5523c.JPG&h=350&w=870&v=1512842132" /><img src="" /><br /><br />The peak of first flowering for Hazel used to be at 13 February in the period 1900 till 1968. Only 0.5% of the observations were done before 31 of December. Since the start of our current Dutch phenological network '<a href="https://www.naturetoday.com/intl/en/observations/natuurkalender">De Natuurkalender</a>' in 2001 the first flowering observations peak 20 days earlier at 24 of January and already 4.5 % of the observations is done before 31 December. This year is extremely early due to the combination of a very warm October and very warm November with before that a relatively cold September. Facinating developments. <br /><br />What is the Hazel doing in your area? Please make also a time-lapse video with the GrowApp of the Hazel in your area and add the #hazel in the comments field so we can easily filter all hazel animations on <a href="www.growapp.today">www.growapp.today</a>.<br /><br />Kind regards, <br />Arnold van VlietArnold van Vliet2017-12-11T08:59:02ZThe 2017 growing season of a Dutch birch captured by the GrowAppArnold van Vliethttps://www.globe.gov/en/c/message_boards/find_message?p_l_id=18703103&messageId=364361872017-12-11T08:47:59Z2017-12-11T08:47:15ZWe have just uploaded a translation (thanks to Marcella) of a Nature report on the analysis of the change in greenness of a Birch tree that I'm following with the GrowApp. See the full story at <a href="https://www.naturetoday.com/intl/en/nature-reports/message/?msg=23923">https://www.naturetoday.com/intl/en/nature-reports/message/?msg=23923</a>.

More and more beautiful time-lapse videos are appearing and showing the spectacular seasonal changes of plants/trees. Next to the ecological and aesthetic value of these changes we use these time-lapse videos to extract information on changes in greenness from different locations during the year(s). Below I have included a graph that shows the change in greenness values for a number of birch trees from different locations in Europe. Below the time-lapse videos that I included in this post, I have added a graph that shows the greenness values that I extracted with the free software Analysing Digital Images (ADI). See <a href="https://www.naturetoday.com/intl/en/observations/growapp/education/educational-assignments">point 5.3 on this page</a> for instructions.<br /><br /><img src="https://images.e-vision.nl/naturetoday/images/original/65e09207-214a-4d32-84f7-e40b41b14bc1.png&v=1509394066&op=noop" /><em>Change of greenness values of four different birch trees in four different European countries based on time-lapse videos made with the GrowApp in the growing season of 2017.</em><br /><br /><strong>Czech Republic</strong><br />The, by far, most intense series of a birch I found so far is made by the Manesova Otrokovice school (#birch #GLOBE #EPS #ManesovaOtrokovice #PavelBroza) in Sazovice located in the Czech Republic. Since the start of the series on 19 May 2017 over 100 photos have been added to the time-lapse video. Almost one every day. The greenness values so far do not show a clear seasonal signal (blue dots in graph). The series started when the tree was already completely green and only now the autumn colouring is taking place. The observation on 14 September clearly seems to be an outlier.<br /><img src="https://phenology.geodan.nl/uploads/fbe704b6ea1606e557dccbe31617fd66.gif" /><img src="" /><br /> <br /><strong>The Netherlands</strong><br />The time-lapse video below is made by myself. The birch is located next to my cycling route between work and home in Bennekom. I made the first photo on 30 March 2017, just before the start of leaf unfolding that started on 7 April 2017. A nice series is developing (yellow dots in graph at top of page). A clear seasonal signal is becoming visible in the greenness values.<br /><img src="https://phenology.geodan.nl/uploads/6cea4a5a4988dc43e58f4784d1dabc6e.gif" /><img src="" /><br /> <br /><strong>Finland</strong><br />The birch in Helsinki (#koivu #sirkkakoivu) only starts to unfold its leafs on 17 May 2017, one and a half month later than the birch tree in the Netherlands. After the 28 May the series stopped and a new photo was added on 23 September.<br /><br /><img src="https://phenology.geodan.nl/uploads/2e752421b5428dec81d29ddd34ac1323.gif" /><img src="" /><br /> <br /><strong>Croatia</strong><br />The time-lapse video below is from a small birch tree in Klenovnik, Croatia (#breza, #klenovnik). The first photo is taken on 12 April 2017. Then the first leafs were already on the tree. Several photos have been taken till half June and then one again one at 28 September and one on 12 October when almost all the leafs where from the tree.<br /><br /><br /><img src="https://phenology.geodan.nl/uploads/28cc2cf939e959ab19133a05e15d05b9.gif" /><img src="" /> <br />To all GrowApp users: thank you for all your beautiful photos and time-lapse videos.
