To find the experimental probability that the next cactus identified will be a prickly pear, you can use the formula for probability:

\[
P(\text{prickly pear}) = \frac{\text{Number of prickly pears}}{\text{Total number of cacti}}
\]

In this case:

- Number of prickly pears = 74
- Number of other cacti = 142
- Total number of cacti = 74 + 142 = 216

Now, substitute these values into the formula:

\[
P(\text{prickly pear}) = \frac{74}{216}
\]

To simplify this fraction, both the numerator and denominator can be divided by 2:

\[
P(\text{prickly pear}) = \frac{37}{108}
\]

Therefore, the experimental probability that the next cactus identified will be a prickly pear is:

\[
\boxed{\frac{37}{108}}
\]
