evaluated and protected. The rules are complex and hard to interpret. Hedgerow

Assistant guides you through the survey procedure, telling you which species to look

for, which parts of the hedge to survey and which features to record. For

environmental surveyors it saves time, work and money.

Step by step hedgerow evaluation.

Lists of Red Data Book and Scheduled species.

Full texts of relevant legislation.

Advises on which parts of the hedge to survey.

On line help to interpret complex clauses.

12.11 Simply Growth

Simply Growth

 is a windows program to analyse growth curves from length and/or

weight data.

The program will fit and plot von Bertalanffy, Gompertz and Logistic growth curves to

your data. These curves are used to model the growth of a wide variety of organisms

but are not simple to fit, as they require the estimation of a number of parameters by

non linear regression.

Particular care has been taken to allow data to be quickly and easily imported from

spreadsheet programs such as Excel and the plots can be exported in a variety of

forms .

12.12 Simply Probits

Simply Probits

 is a windows program to estimate lethal or environmental

concentrations using toxicity data.

The program offers two types of analysis.

Lethal dose calculations: a probit analysis of the survival of organisms exposed to a

range of concentrations. Conforms to ISO/DIS 146609.

Growth analysis: studies the inhibition in the growth of organisms exposed to

different levels of a compound.

Conforms to ISO 10253 .
