BMC Women in Adventure Film Competition

I am thrilled to announce that my film Pioneer has been listed in the BMC Women in Adventure Film Competition 2021.

Celebrating the early pioneering women who paved the way allowing us all to have the opportunity to go outdoors, explore and experience the world. Pioneer is about inclusivity; how anyone from a minority can make a change, how the great outdoors and nature is there for everyone to enjoy.

I wanted to combine my love of period pieces to my love of walking, the outdoors and being surrounded by Nature. So this piece is less about climbing the highest mountain but more about the ideal that Nature is there for everyone to enjoy.

One of the prizes is done on views so I would love for you to watch and share if possible. To find out more about the competition and watch some of the other great films here.

Thank you for your support. Holly.

Holly’s Tree Identification Record Book

This record book will help you identify and become familiar with 30 British tree species.  Of these 21 are native, 5 are naturalised or commonly found broadleaved trees and there are 4 commercial exotic conifers.

The idea of this booklet is for you to gradually build up knowledge of British trees. You will note that the correct conventions are used for plant naming, i.e. Capital letter for the generic name and small (lower case) letters for the specific name.

The trees in the Record book are listed in the following order:

  • Native trees (mainly deciduous)
  • Introduced or naturalised none native broadleaves
  • Commercial exotic conifers

Family and the outdoors

You are never alone.

Family is a word which derives from the latin familia, meaning servant, to serve. I am lucky enough to have a big family and we have been together during lockdown, including our four legged family members. We look after each other, make sure each member of the familia is safe. Which made me think about those during this last year who are alone.

Loneliness can make your body feel cold, it can suppress your immune system putting you more at risk of disease. However, I found that the great outdoors can help combat it, Doctors are prescribing time in green spaces, it can improve mental and physical health. I always feel more proactive after going for a walk, hugging a tree and just sitting in the local woodlands listening to the sounds of the woodpeckers, robins and great tits as they sing above my head.

Even if you can’t be together with all family members, for whatever reason, know that they are there with you in mind, spirit and soul.

Work with Holly

It is known that spending time outdoors and in contact with the natural environment can have positive effects on physical and mental health (Pretty et al 2005, Seymour 2003). With tourism lower due to the recent pandemic, it is important, now more than ever to get people back outdoors. Regular walking improves mood, reduces anxiety and helps with sleep (Department of Health 2004, Mind 2008, Walking the Way to Health 2009). 

By working with Holly you will get some beautiful, authentic marketing material to show off your National Park, AONB, SPA, Heritage Site or Wildlife Sanctuary to your audience and to help you encourage more people back out into your natural space. 

This bespoke content is yours to use in perpetuity on your website, social media and in other marketing material. If you would like to know more, then please contact Holly below…

Why I love New Zealand

the mountains
the wildlife

the trees
the sky

take a moment

Take a moment and think about some of your best memories. Chances are they are action or views, not necessarily words.

For me, New Zealand has many memories. I love hiking the trails in Arthur’s Pass where Avalanche Peak sits shadowing over the valley below watching you drive from East to West coast. I love the mountains in New Zealand, the volcanoes and all their stories.

Poor old Mount Taranaki who was banished to the coast.

I love the wildlife, the flora and fauna which fills every nook and cranny. Wherever you look there are wild flowers or domesticated flowers home to wild insects and then there are the trees. Oh the trees of New Zealand, especially the Kauri tree (Agathis australis) reaching 50 meters high gaining its nourishment from the leaf litter close to the surface.

Then there is the sky.

The sky which I can stand and look at for hours on end. Whether it’s the cirrus clouds whispering over the lakes or the cumulonimbus clouds forming around the mountains. Even at night, on a clear sky, watching the stars overlook the planet whilst we sleep.

I love it all and I wish the country a safe recovery from current situations.

Camping in the snow

1am, the field

It’s meant to be -3 overnight so I thought why not camp out. The warm, cosy van is just around the corner, but now is the perfect opportunity to test out some kit, before heading to the Alps (once restrictions have lifted).

This kit is suitable for a wild camp backpack adventure.

I have chosen some of the lightest kit including the single person River Elk tent which was really smooth to put up. I love this style of tent where the inner and outer go up in one. Makes something which could be a faff, easy. As the temperature dropped I was in my base layers in a Serac 600 sleeping bag. I was very comfortable, as the comfort level for this bag is -7, for women.

The sleep mat, weighing 485g has a diamond pattern which I haven’t tried before. I found that this mat would be great in the summer, however I sleep on my side and I did feel my hip slide into the channels overnight so could feel the cold. Even though this mat might not be the best style for me, I would say for a summer walk for someone without the pointy hips this mat would be a great lightweight addition.

I haven’t cooked here as I am adhering to lockdown measures and camping at home.

So even though we are hunkering down at home, we can all still have some mini adventures without having to travel. I am just working out what is next – watch this space!

to conclude,

What is a Chordate?

There are 5 main characteristics which put all the species within the Chordata phylum, they all have evolved to have a notochord within their bodies, they have this instead of a shell, this notochord when combined with the Dorsal Hollow Nerve Cord provides an internal support which the fluid tube of nerve fluid will then pass from top to bottom of the animal, acting as a spinal cord.

These are ancestors of humans as the boned spine of us today can be linked back to the Pikaia, the very first back boned animal. There is also a pair of openings through the pharynx present which shows that they are filter feeders, they all have blocks of muscle which extend into a post anus tail, the muscle surrounds the notochord along the whole length of the animal.

Pikaia

The basic traits of this phylum are that all the species are bilaterally symmetrical; they are segmented and have developed a gut tube, their coelom. The Devonian Period was a time in history where fish developed in leaps and bounds! They were first thought to have evolved in the Cambrian explosion, Levine (2003). The Pikaia fossil was found in the Burgess Shales, the fossil shows us many ways of how this organism lived.

We can tell that it swam along the sea bed using its tail as a fin, because of its mouth area, no scientist has distinguished what it exactly ate but it looks like it just fed off particles in the water and near the sea floor. Being one of the first fossils having “soft parts” it is a major discovery, Paleobiology.si.edu (2011).

Urochordata (Tunicates)

Sea Squirts are marine animals which both are solitary and colonial, depending on the species. They are sessile animals and have a unique feature; where they settle on a rock head first, their tail disappearing overtime and once stuck they then move their mouth moves back upward to catch passing particles to consume.

The hermaphrodite species release sperm and eggs. The eggs are about a third of one millimetre and kept in the body until they start to evolve within a few weeks. A siphon takes in the passing particles to be absorbed; this is known as suspension feeders.

Cephalochordata (Amphioxus)

Lancelet worms are filter feeders with no brain at all and are a marine subphylum, they swim and can bury themselves in the sand. All of the characteristics of a chordate are present, including the post anal tail. They do however have poor eyesight and lack of brain, but as they have sensors they are not really needed. So instead of wasting energy and time developing them they have evolved to have superior “feelers” and this allows them to hunt efficiently, Barnes (1994).

There are only about 30 species of Lancelet worm present they can grow up to about 7cm in length. Their cirri (tentacle feelers) are used as sensors for particles in the water, the pharynx has lots of gill slits which allows water to pass. Once absorbed the water passes out through the atriopore, Sherwood (1977).

Craniata (Vertebrates)

Ggnathastomes have two main types within; these are the Hagfish that secrete slime as a protection from predators and the Lamprey which have a cartilage dorsal cord and have seven gills present on each side. They are a parasitic species. The main difference is their habitat, Lampreys can live in both freshwater and oceanic but Hagfish can only live in Oceanic waters.

Lamprey – Anjanette Bowen/U.S. Fish and Wildlife Service

Their bodies have been developed to have a lower salt concentration in their bodies compared to in the waters which is why if put in a fresh water environment they wouldn’t survive. You know these are carnivorous because of their sharp toothed tongues, which pierce through their prey. The Hagfish can tie itself in a knot as a way to release itself from prey if caught and also to wipe the slime off of its body to make a quick escape. They were first thought to be hermaphrodites but research shows that this is not the case, they are born with both sex cells but only one takes dominance, Biglow (1948).

So there you go, I hope you enjoyed learning a bit about our wonderful world and those that inhabit it!

What is soil?

There are many elements that contribute to the formation of Soil and they are: climate, time, organisms, parent material, relief. Climate is the most important with determining soil characteristics. Soils are a valuable non renewable source. 

Horizons are the different levels in the soil’s profile, in each level something different is happening within the soil. It is the downward movement of material by leaching and eluviations that creates the layers within the soil profile. These horizons show the major inputs and transformations from the soil. Eluviation is the downward movement of particles in the soil.

H – is the top layer of organic material which is saturated with water

O – decomposed litter which is mixed with minerals

A – this is the mineral horizon

E – this layer is depleted of material and is mainly silt or sand particles, therefore resulting in a lighter colour

B – it is the subsurface, the zone of accumulation

C – the layer of unconsolidated parent material

R – this parent material is hard bedrock eg limestone

H – Humus = organic matter. Organic matter is dead organisms and plant remains. There are three stages to a humus layer. From top to bottom layer one is Mor – twigs, leaves etc, middle layer is Moder – which is the partly humified remains and the bottom layer is Mull, which is well decomposed organic matter. Humus is very stable yet very variable, it is known as a chemical junkyard. 

Soil composition

Air 20-30%

Water 20-30%

Organic Matter 5%

Mineral 45%

Clay has the smallest soil particles.

A Platy soil structure is produced after a lot of freezing and thawing in the soil. 

Gravitational Water – removes nutrients from the soil as it moves down macropores, it takes nutrients lower, moving it away from the plants, making growth harder.

Capillary Water – it’s found in the micropores of the soil and therefore is found higher as the plant roots can find this water. 

Hygroscopic Water – is different as it is useless for plants as it is in vapour form.

Water in the soil; www.growflow.com.au

Gleying (mottling) is due to waterlogged soil.

Podzol – have a Ea layer which is bleached by the leaching of humic oxides and also has a Bh layer, this layer is blackened by humic oxides. (Chapman J. 2002) it is founds in a cool, humid and temperate environment. Rainfall is a major input. 

IronPan – has a really thick dark humus layer. The soil below has a glacial origin and is called induration. 

Rendzina – bright white soil, its chalky and good for grasses.

Gleysol – water logged environments, it provides anaerobic conditions. 

Gleysol © ISRIC, http://www.isric.nl

Ferralsol – an old soil, it has been thought high levels of weathering, it is a bright red colour due to mineralization. 

Histosol – a soil which has a lack of O2. It is very dark due to rapid accumulation of organic matter. It has a very hight water and organic matter input. 

Spodosol – lower layers are stained with aluminium and iron oxides, due to the acidic soil formed by the amount of needles from coniferous trees which decompose and it is these needles that form a weak acid during decomposing.

The calcification process occurs when the soil has a high organic matter amount and there is calcium carbonate precipitated from water. This produces a bit of leaching leading the A horizon to become dry, yet organic rich. The vegetation is mainly grassland.

Peds are small particles in the soil that form clusters and therefore making bigger pore spaces, for water and air. 

Temperature regulates the rate of decomposition. Therefore showing that Evapotranspiration and rainfall affect the movement of water and leaching. 

Soil structure – the proportions of sand, silt and clay and the bonds which form aggregates 

Soil Colloids – are clay minerals that have a large surface area and a positive charge, they include hydrous oxides of iron and aluminium. 

The cation exchange capacity (CEC) is the soils ability to absorb the cations. A soil with high CEC has a high change of particle collision. A clay rich, high humus soil will have the most collision. (Ashman, 2002)

Rainfall leads to leaching, and when certain types of rock are decomposed by this process a process called lateralization occurs, it deposits large amounts of ferric hydroxides and aluminium. (http://www.bibarch.com/concepts/Theory/Matrix.htm)

Aluminium is toxic to plants as it inhibits cell division, for example shorter roots are made, reaching less horizons, making it easier for them to die in a drought or during soil erosion. 

When areas are totally water logged all the time this dark, thick peat layer is found and it is due to the amount of bacterial activity, this soil is found normally in low lying areas where rainfall is high. Iron is released from the decaying organic matter changing the colour of the soil because of oxidation. This process is called Gleization.

Salt precipitates from the water making saline soils, like the soils you will find in dry, warm conditions, the process where salts accumulate in the soil is called salinization.

Nutrients are a substance used by an organism for food. They need certain amounts to be at full potential. The nutrients they need are below. The three most important nutrients are Nitrogen, Potassium and Phosphorous. Soil nitrogen is found in the soils organic matter, it is found in the form of ammonium and nitrate. If a soil has too much water it leaves the plants with nitrogen deficiency. 

Macro Nutrients 

C & O = Atmospheric

PO, SO, NO – Anions = Soil Sources

NH, K, Ca, Mg – Cations = Soil Sources

Micro Nutrients 

All are Soil Sources –

Mo, BO – Anions

Cl, Fe, Mn,Zn, Cu – Cations 

The exchange of nutrients within a pool is referred to as turnover. 

Soil Surveys map the distribution by measuring the soil and inspecting it.

Soil degradation 

Catena is…

The sequence of soils that occupy a slope transect, from the topography divide to the bottom of the adjacent valley. (Smithson, 2002) 

Bulk Density = weight of soil per unit volume

Air Capacity = percentage of volume occupied by air

Water Holding Capacity = water held once drained (using gravity)

Soils can become contaminated by many different human influences, they include –

  • Sewage sludge, pathogens
  • Metals from mines,
  • Landfill sites,
  • Fertilizers

Elevate chemical levels in the soil is counted as contamination. These contaminates can be divided into organic and inorganic compounds. Organic include, pesticides through leaching, PHA. Inorganic includes, acid rain, metals and radiation. 

Soil Erosion

It happens in two main steps: 

  1. Is the dislodging of soil particles
  2. The movement of particles to a new location 

Soil erosion increases the pollutant risk, it is the least renewable physical component of an ecosystem. Erosion is important to understand as it reduces plant root depth, leading to less plant species in that area, it is however a natural process but human activity does increase it. 

Weathering

Soil is formed when the mineral material from rock and organic matter combine. There are many different processes which break up soils.

  • Physical Weathering 

Two main types are Thermal where heat causes expansion and the second is Mechanical, e.g Frost Shattering. 

  • Chemical Weathering 

Hydrolysis – H20 separated into two molecules that attack the mineral bonds within the soil.

Carbonation – this is basically accelerated hydrolysis due to biological activity.

Hydration – the absorption of water e.g like pasta. 

Dissolution – the minerals dissolve from the soils.

Oxidation and Reduction – is the loss and gain of electrons through the contact of air/oxygen.

Recycled Parts in the Van Conversion

We did buy a lot of things brand new like the stove, sink and fridge, but I wanted to write a blog about the parts that we managed to recycle.

The flooring was taken up from an old caravan conversion we did a few years back. We managed to reuse the underlay for the van flooring and also for the sliding door curtain padding. We knew the side window will be where we lose the most of the heat so wanted to make sure that we insulate it as best as possible.

The silver bubble foam stuff was also ripped out of an old project and used to insulate the bulkhead and the little bit about the cab. Then lined with carpet.

We reused an old piece of memory foam for the seating in the living area and also cut out some head rests for the cab. The material used to cover these were also taken from an old pile of fabric we had laying around.

We also used the old wood from the van itself. Finally, the last thing that we reused were the bed slats from an old bed. These were then just cut down to the right size.

It is important to us to reuse items but for the build we wanted to achieve it couldn’t all be done with recycled materials.

When we finally get to leave on our Europe road trip, I want to add up the total milage and work out the co2 emissions and plant native trees in Britain to offset our carbon footprint.

Additionally, I would like to work out the mileage that all the brand new stuff has come from and offset that too. But I feel this will be more difficult! I might just have to work it out from the shop to the house, instead of from the source to the house, which is probably impossible.
