Adventurous Silsden scientist Jemma Reinsch faces the first of two big challenges this weekend.

On Sunday she begins a 24-hour challenge to climb the UK's highest peaks -- Scafell Pike, Ben Nevis and Snowdon -- to raise money for an expedition to Tanzania.

In Tanzania, Jemma, 22, who has just graduated from Stirling University with a degree in environmental science, will carry out conservation work.

She says: "The main aim is to collect data on the biodiversity of fisheries and plants used in the local community."

Jemma, who lives in Low Park Green, Silsden, is one of a team of scientists travelling to East Africa in January and carrying out three months of research.

Between then and now she has to raise £3,000 to finance the trip. The peak challenge is her first fundraiser.

Jemma says: "I first thought I would do the three peaks in the Dales, then thought lots of people do it.

"I felt if I did the national thing and had a time limit people would be more interested. It is possible in 24 hours -- I've worked out the times."

The former South Craven School student will be accompanied by friends James Rushton and Timothy Sutton, who have done Duke of Edinburgh Award challenges with her.

Jemma has climbed all three peaks on separate occasions, and regularly walks in the Dales and Lakes.

Anyone who can offer sponsorship for her Tanzania expedition should either e-mail her on jemmareinsch@hotmail.com or telephone 01535 654510.
