The weather today was glorious…

… and I followed the vascular plant (flowering plants and ferns) team of Neil, Daniel and Alex to a site about an hour and a half away from the hut. I decided to record each of the species they found and turn it into a film to give you an idea of the variety that we’ve been able to collect.

 

Day-13-PIC-2.jpg

 

In the film below, I’ve listed the family, genus and species (where possible). This highlights why it is so important to collect samples of the plants - without taking them to a herbarium and comparing them with other specimens it can be difficult to identify exactly what is there.

 

The top line is the family and the bottom is the genus and species (if we knew it straight away, of course!) Please note, I made this video so if anything is wrong it is my fault not Alex’s!

 

 

Just my luck - this site only provided 44 species which was quite a poor haul compared to the others we have had. Our best day has had over a hundred different species of vascular plant and that’s not counting the lichens and bryophytes Holger and Jo are also collecting.

 

On days where more species are collected, we sometimes have to do the pressing back at the hut and the dinner table is transformed into a mass of newspaper and plants

But today we got home early so Alex made us a pasta dinner.

Species of the day – take your pick from any of the ones in the film above!

 

Tomorrow we are walking back down the mountain to the first hut we stayed in before heading back to the entrance to the park and the drive back to INBIO.

 

I feel quite sad to be leaving our hut in the Valley of Silence as my time here in Costa Rica nears its end. It has been an amazing place to be based and I feel very attached to the forest and our place in it.

There's no doubt about it, when you join us for our Big Nature Day extravaganza this Sunday on 22 May, you'll get your hands dirty.


But that's pretty essential if you're going to help our scientists and wildlife experts in the Big Nature Count to find and identify how many different species of plant and animal there are in our Museum Wildlife Garden. It's a 24-hour census - or a bioblitz race for those familiar with the term -  to celebrate International Day for Biological Diversity and International Year of Forests, as well as the start of the UN's Decade on Biodiversity.

As Stuart HIne, manager of our Centre for UK Biodiversity says: 'We have many visitors to the Wildlife Garden, from our regular human ones to more unusual visitors such as honeybees, damselflies and hawkmoths. In fact, since the garden opened in 1995, we’ve recorded more than 2,000 different species and it would be great to know what's about on Sunday.'

 

Along with the regular Big Nature Count guided tours, worm charming (above) will be a popular highlight of the day. There are two sessions at 12.00 and 15.00. The recent rain should help lure the worms to the ground's surface. Although we're hoping that the sun will shine gloriously on the day, of course.

Other garden action includes the Bugs Count, Tree Hunt, moth trap checking, investigating pond life, and check out the Bee Tree.

 

Inside the Darwin Centre, head over to the Specimen Roadshow to identify your favourite specimens (or bring in a picture) and there are nature talks in the Darwin Centre's Attenborough Studio.

Look around and above, plants and trees may hide moths (like this Poplar hawkmoth, left) and butterflies. There are eight common trees in the Wildlife Garden to identify. Select images to enlarge

Take pictures on the day

Most important of all, though, bring your cameras or have your mobile phone to the ready to snap the species you do manage to spot. With these, you can help us create a spectacular Photo Wall in the Darwin Centre atrium at the Interactive Media area. You can print your pictures here for the display or upload them with your comments to our Big Nature Day guestbook on the computers available or at home afterwards.

 

Big Nature Day is a free, drop-in event that will appeal to all ages, but you'll need to book on the tours and worm charming sessions.

 

When you arrive at the Museum head for the West lawn or Darwin Centre atrium where you'll be directed to the Base Camp in the Darwin Centre Courtyard, the hub for the day's activities, and where you can see lots of special displays.

Yann Arthus-Bertrand film treats at the French Institute on 22 May and on the International Year of Forests website

If you want to see an amazing nature documentary by The Earth From Above photographer Yann Arthus-Bertrand, head over to the nearby French Institute for a special free screening of Home at 18.30. Our Museum botanist Sandy Knap is introducing the film. Although it's free you need to book a place on their website.

batperson-ally-pally.jpgLondon’s Alexandra Palace Park played host to a Wild Day Out on Saturday 5 June. Natural History Museum and OPAL scientists went on a mission to record as much wildlife as they could in the park over 24 hours, including some strange batmen, like this one. OPAL is the Open Air Laboratories Project network.

 

Over 8,000 people joined in the Ally Pally BioBlitz, making the event a huge success. The final species count is to be confirmed but is expected to be in the region of 700.

 

The bioblitz event was partnered by the BBC who helped to rally lots of local people to assist with pond dips, worm charming, nature surveys and other activities in a bid to record all the plants and animals that live in the park. There were also arts and crafts activities for kids.

For the uninitiated, a bioblitz is a kind of wildlife hunt against the clock, and anyone can join in. It can be a really big event in a large public space or a small one in your garden.


As well as the Ally Pally event, our Museum scientists and OPAL researchers staged another bioblitz at South Devon's Mothecombe Beach on 11 June. Here, local residents, schools and holiday-makers helped scientists record over 700 different species in just 28 hours.

kids-alexandra-palace-bioblitz.jpgBoth bioblitz events are part of our national International Year of Biodiversity in the UK celebrations.

 

There are lots more bioblitzes happening around the country and you can find details on the National Bioblitz Programme 2010 website

OPAL, the Open Air Laboratories Project network, run lots of surveys and citizen science activities you can join in your local area and online. They have a base in our Angela Marmont Centre for UK Biodiversity.
