Need For Feed Disaster Relief has received more than 800 applications since summer began and opened the door for scorching temperatures to wreck havoc on pasture growth. More than 660 have been lodged since January 1.

Logistics coordinator Cassandra McLaren has called on the government to provide suitable vegetation maps so animals living in a dust bowl could be helped first.

"By the 6th of January we had more applications than we did in December, and by the end of the month we had more than 410 applications," Ms McLaren said.

"They are from across the state, you can't pinpoint a certain area. The recent heat, even to the areas that have had a bit of reprieve, is showing the negative effect on the grasses.

Ms McLaren has also urged the government to create mapping software to help charities plan hay runs.

She has been using a secure free mapping program to plot each depot drop-off location, but it is not ideal.

The Australia Day run alone, which helped farmers across 200,000 square kilometres, took 14 hours a day for two weeks to plan. 

"The mapping system is limited, we found a program that would be suitable but it had an annual fee and even with a discount it was going to cost around $10,000 and we can't put money towards that when there are people out there who are waiting for fodder assistance," she said. 

NSW Primary Industries Minister Niall Blair has asked the NSW Department of Primary Industries to investigate possible solutions. 

"We're getting that close with our technology that we can get down to a farm by farm scale but there are issues with what you can do with that data and who you can give it to," Mr Blair said.
